After placement of the 'add-a-leaf', the stock u-bolts were not long enough to allow for a full nut's length of thread. Both I and the Ford Dealership, doing the installation, agreed that this was not as safe as it should be; a full length minimum should be required to avoid any undo stress on the threads holding the spring assembly onto the axle. Longer u-bolts, not provided in the Stage-3 Add-a-Leaf kit, were obtained and used to complete the installation.

I have a capper, wood bench, extra battery etc...always in the truck, so with a full load it really starts to sag, or when towing, especially with my leveled front. I wanted to get rid of my sag and get some extra weight capacity and ended up giving this a try. First, it raised my back end about 1 3/4-2 inches, so I have a bit of the factory rake back. Second, I can have a full load in the back without sag. The ride isn't any worse than before, no bounce in the back. It's over 40 inches in length so it isn't some tiny spring that makes the ride rough..I would buy it again without hesitation.

Install time was 3 hours including jacking and supporting vehicle and locating tools. I installed the leaf after installing 2.5 front leveling kit. The front leveling kit after alignment gave .5 lift to the rear. After the add a leaf I gained 1. Truck looks and drives amazing, not rough at all !!

Very easy to install (with car lift), I had an issue with squat do to carrying my RTT w/ bed rack, drawer system, fridge w/ fridge slide, 100ah Deep cycle AGM batt, camp stove....etc. these remedied that quick, gain my body clearance back. Would recommend these over helper springs.

Cannot comment on the install, strictly because $200 for 4wheelparts to install was cheaper than me dragging the jack out of the garage. Previously I had leveled the truck with 5100's. When I towed my 5k lb trailer I would have 2" sag in the rear. I decided to upgrade to a 10k lb trailer and knew I needed the help. As you can see from the picture, these things rock! I picked up just shy of 2" in the rear after install. To address the ride.... Shut up. You want a Cadillac, go get one. Its a truck. To say the ride is "slightly" more chopper would be a stretch. I will take the ride over looking like an idiot going down the road with my rear bumper dragging the road with a load on it.

Excellent product and did exactly what was advertised. I hauled 1,500 lb. to 2,000 lb. pallets across town about 20 times recently and afterward I noticed my truck had permanently sunk 1.5. I bought this product to increase the hauling capacity and to get the lift back and it worked perfectly. I had a local company do the installation and they had no problems at all. It might be difficult to see the lift difference in the before and after pics because its only 1.5 , but its there if you look close enough. And I could tell immediately in person. I like knowing that I have that extra hauling capacity. I noticed no difference in the ride quality after installation. Thank you!

This is just what I was looking for. I installed the Rancho Quick Lift Loaded combo on the front to level my truck but I was not satisfied with the look. Instead of installing an airbag suspension on the back like my previous truck in went with these and so far I am very happy with my decision. Install was a breeze and had no issues.

I had installed fox 2.0 coilovers on my truck for about 1.75' of lift leaving the rear nearly an inch higher than the front. A leer topper and 20k miles later the rear factory 1.5' block had allowed the back of the truck so sag nearly level with the front. Load some wood or gear in the back and the truck would go nose high and even hit the rear bump stops on rough surfaces. I decided to grab these AAL's and give them a try. I removed the factory block and put these in their place. The rear is back to an inch rake over the front and the ride is so much better! Possibly a little firmer ride but not harsh in any way and handling is much improved. If I ever buy a new f150 I will immediately remove the factory block and put these in. Not one complaint, easy install and a quality product that's worth the money. Took about two hours in my garage. If you put as much as a golden retriever in the bed of your truck you need these!

I have a 2018 F150 XLT. I purchased the truck and immediately installed a 2.5” front leveling kit. This set my truck within a 1/4” of perfect level. When towing a UTV my truck would squat significantly in the rear. I started looking for options to maintain the desired stance. After reading reviews I decided to purchase the add a leafs. I installed the add a leafs my self using jacks and jack stands. It took me about an hour. While installing I removed the factory blocks(1.25” blocks) and this set my truck right at 40” in the rear. This gives my truck a 3/4” rake and increasing the rear height by 1/2”. The ride quality hasn’t suffered much. You can feel a little stiffer ride but only slightly. The increased stabilization while towing is worth the slight stiffness in the ride. At 4000 miles in I’m very pleased.

After installing my Bilstein 5100 Leveling kit at the second from highest setting, the truck would squat with barely any weight in the bed (2.7l eco). I carry a deep tool box with about 200lbs of tools at all times and it felt like the truck was back heavy. Once I installed the leaf (left stock blocks in) the truck almost has a stock rake back, rides better, handles weight better, and tows better.

Added the perfect amount of lift to my truck and compensated for the extra weight of the Leer Cap I added. The Fox 2.0+the leer were a little too much to keep the truck level, so this provided a small amount of rake now that it has settled out. The only thing that would make this kit better would be included U-bolts for the application as I felt they could have been a little longer.

Works great, leveled my truck out perfect. I have a fiberglass topper on the back that made a difference in the stance, she now has the stance of a real truck with the add a leaf. Can't really tell a difference in the ride quality either, still rides great. Took about 4 hours to do both sides with no power tools. Pretty easy job.

This item is supposed to raise the rear end of your truck 1.5-2". After installing these leaf springs and a 2.7" lift to the front, my ride went from a 1.5" rake to a 1.25" squat ... meaning the rear end was lifted a whopping 0.05 inches. Additionally, the whole point of add-a-leaf springs is to prevent sag under load. Unloaded, there was 1.5" is space between the bottom of my Timbren SES and its base plate. After loading half a cord of wood, there was no more space in the SES. As far as I can tell, these leaves have done absolutely nothing for my truck's suspension. The only good thing I can say is that they're heavy steel. Unfortunately, they are also difficult to install, since you have to take your existing spring pack apart to install these leaves right above the bottom leaf in the factory spring pack. This product is not even close to the performance and convenience of Hellwig's Helper Springs and are actually more expensive. I wish I had found out about the Hellwig springs before I bought these add-a-leaf springs.

For the price point these leafs are super legit. Install per side is 30 minutes tops if you're mechanically inclined. I installed them and immediately towed 9k on stock shocks with no squat with 2" leveling pucks (previously installed before leafs) Before the Add a leaf, I had 2" leveling puck making full level no factory rake. After the add a leaf settled it return to factory like rake with the 2" leveling puck still installed, so if you're going to install these with no leveling or other suspension work, your rake is going to be utterly ridiculous.

My 2019 shocks felt mushy after 45K miles, so wanted to put some new shocks. At the same time wanted my truck to be little higher than factory setting. This is perfect combination if you ever want to upgrade your new shocks. Order Bilstein 5100 complete kits F&R, Spring rear add a leaf kit, and SPC HD camber & caster kit. After all the install, it lifted my truck 39" front and 40" in the rear (ground to fender). Basically 2" lift front and 1" lift in the rear, total of 39" F and 40" R. The best upgrade I've done for my truck. Rides very good, feels really grounded, little harder than factory shocks, but it feels good over freeways and local streets. I highly recombed these combos. Later when times comes, I'll do upper and lower control arms, nothing fancy, I like it just the way it is. Looks great and drives great.

Asked by: Al - 6/27/2023
Customer Answer It really depends on the shocks extended length that you are currently using. Most shocks have a max extended length so you should would have to be able to extend another 1.5" beyond what they currently are. Give us a call to go over your current setup so we can see if you would need longer shocks to accommodate the extra lift. 623.434.5277

Asked by: Adam - 1/22/2023
Customer Answer They cannot. If you need more ride height than what this add-a-leaf provides, you can pair it with a larger rear block of some sort. Just keep in mind, the factory shocks won't be able to handle that ride height, and you will need an aftermarket solution.

Customer Question I have a friend that installed the AutoSpring Add a Leaf and once it settled it settled down .75” on the left and 1” on the right. Is that uncommon? With a stock block and stock tire size it’s sitting at 40” ground to fender on the left and 40.25” ground to fender on the right.

Asked by: Jade - 4/8/2022
Customer Answer It's not uncommon for the left (driver's side) to settle more than the right, due to the fuel tank being on the left. If you measure again with the fuel tank close to empty, you'll likely find it a bit more even (especially if your truck as a 36-gallon tank). If you think you have another issue, please give us a call directly at 623-434-5277 or email us at [email protected].

Customer Question I have a 2015 Ford F150 Platinum 4wd and just added a leer topper with rack. The truck has a 2.5 leveling kit but I have noticed slight lowering in the rear, maybe 0.5 - 0.75 inches. would this essentially relevel the truck and possibly give it a little rake? Thanks

Asked by: Richard - 8/30/2021
Customer Answer This somewhat depends on how heavy your topper is. Without constant weight, this add-a-leaf tends to provide about 1.5" of rear lift after break-in. With a constant load, you should at least get close to where you want to be. Personally, I think you'd win back a bit of rake, though it's hard to say how much.

Customer Question My ride is a 2020 F-150 XLT 3.5L Eco-boos.t I have a 2.25in ready lift on the front suspension with a 4in ready lift rear block on the rear axle along with a RAS system. My rear shocks are Rough Country V2 (4-7.5in). What size block do I need to reduce to keep the current height of the rear of my truck when I add your add-a -leaf spring. I'm sorry i know I have reached out to you once already but my information before was not clear enough. Thank You, Kevin

Asked by: Kevin - 8/28/2021
Customer Answer In theory, since this Add-a-Leaf adds around 1.5" of ride height after break-in, so you would need to drop down to a 2.5" rear block to keep your current rake and general setup.

Asked by: Salah - 6/27/2021
Customer Answer This add-a-leaf kit will lift the rear of your F150 by roughly 1.5" to 2", and a rear block would not be required. Neither method is inherently "better". Add-a-leaf kits are nice because they give you lift and load support, but they also tend to stiffen your ride by a bit. Rear blocks are nice, since they don't change your ride much at all, but they don't give you much benefit other than the ride height.

Asked by: Tony - 3/10/2021
Customer Answer These add-a-leafs do not change your factory rated payload capacities, GVWR, or GCWR. However, they do offer improved load support and give your truck less sag when pushing your rated limits. According to Auto Spring, the springs provide up to 950lbs of additional load support.

Customer Question How long is the break in period for the AAL to settle to 1.5” of raised height? Also, I’m getting a 2.5” Mammoth level installed on the front of my ‘16 F150, will this combo level me out or leave some rake? (I don’t want any squatting)

Asked by: Brad - 8/21/2020
Customer Answer According to Auto Spring, it takes about 500-1000 miles depending on how you drive it and the condition of your roads. In general, it takes about 2.5" of leveling alone to get the 2015-2020 F150s at a near "dead-level" stance. Adding the Add-a-Leaf would leave you with some front rake.

Customer Question I currently have a BDS 4" lift on F150 XLT 4WD. It has 4" rear blocks. When towing, even with the weight distribution hitch, i'm getting sag. What combination of reduced block size and this AAL kit would keep the ride height the same/similar unloaded and also prevent sag while towing.

Asked by: rhervey - 6/19/2020
Customer Answer That's really going to depend on how much you're towing and how much sag you're getting. In general, a 4" block adds about 2.5" of rear lift. In theory, if you do something like a 2.50" rear block that adds 1" of lift, and then top them off with an Add-a-Leaf kit, then you'll technically get the same ride height (after the springs break in, anyway) and get better load support than blocks alone. However, it's tough to say without knowing about your sag and load situation. Give us a call directly at 623-434-5277 so we can get more specific about your truck.

Customer Question Any reports or feedback that this AAL eliminates "axle wrap/wheel hop" or the vibration/shakiness caused by the soft oem leafers?

Asked by: Hoke - 5/18/2020
Customer Answer They offer less axle wrap and wheel hop than larger rear blocks. Most of the rear-end stability issues on the 2015-2020 F150s are caused by the rear shocks, and upgraded to a nice set of monotubes goes a long way to improving rear handling. Add-a-Leafs can help, though shocks are usually a better place to start.

Customer Question I’m getting rear sag from my truck cap and Decked drawer system (rake is almost gone). I’m going to use the add-a-leaf and also plan to lift the front with coil over leveling struts. I would like a look like the maroon F150 pictured on this product page. Can you tell me what was done to the front?

Asked by: K. Cooper - 5/10/2020
Customer Answer That's Auto Spring's truck, and unfortunately, I don't have exact specs. From eyeballing it, I would make the educated guess that it's running a 2.5" leveling kit up front with how little rake there is with the Add-a-Leafs and topper on.

Customer Question Will the bilstein 5200 rear shocks work with this?

Asked by: Matt - 4/29/2020
Customer Answer If you mean the Bilstein 5100s, then technically no. Bilstein only rates the 5100s for 0-1" of rear lift, while this add-a-leaf kit adds 1.5" of lift after they settle.

Asked by: Dpeters07 - 4/4/2020
Customer Answer In general, since this add-a-leaf kit only provides about 1.5" of ride height, pinion shims, carrier bearing brackets, or any other driveline alignment parts are not usually required.

Customer Question Not sure what direction I want to go on the suspension for my 2019 Raptor. Its currently leveled with a icon collar kit and now the rear sags. Can I use this or something similar to get the rear end up in the mean time while deciding what full kit I want to do?

Asked by: PC - 2/7/2020
Customer Answer Unfortunately, this add-a-leaf kit will not fit 2019 Raptors. It only fits 2015-2020 F150s, due to the different leaf packs. Your better bet at the moment would be a rear block of some sort, though you should give us a call directly at 623-434-5277 so we can get more specific about how much rear ride height you need.

Customer Question How much stiffer it's gonna be? Will any improvement if I upgrade to Bilstein 5100 shock at the same time?

Asked by: Sam - 9/12/2019
Customer Answer Adding an add-a-leaf can stiffen up rear ride quality a bit, but it's not overly bad. Aftermarket rear shocks can help immensely. The Bilstein 5100s can't actually handle the amount of ride height that add-a-leafs provide, and you'd have to go with a different shock option like the Halo Lifts Boss 2.0s.

Asked by: Todd - 8/15/2019
Customer Answer Unfortunately, no one that I'm aware of makes an add-a-leaf or a mini-pack for the 2017-2019 Raptors at this time. Your only options for adding rear height are full leaf springs or a rear block kit, though hopefully we'll see some Raptor-specific add-a-leafs here in the near future.

Asked by: Kyle - 8/10/2019
Customer Answer You should be fine using Hellwig's Sway bar with this add-a-leaf kit, since Hellwig's end links have enough adjustment to compensate for this add-a-leaf kit's 1.5" to 2" of lift. Though you may want to hold off the sway bar install until the add-a-leafs are fully broken in and have settled closer to their 1.5" normal ride height so you don't have to readjust the end links later.

Customer Question for a 2015 F150, 2WD XLT with a towing package, is there a rough estimate of how much added payload capacity I'll get with this kit? I've been hauling a lot of paver stones, decomposed gravel, etc. and could use a few hundred pounds extra capacity.

Asked by: JSom - 7/24/2019
Customer Answer Technically speaking, this add-a-leaf kit won't don anything to increase your truck's GVWR or GCWR. However, they will help support more load in your bed than the stock leafs alone and help reduce the amount of sag when the rear end is loaded. According to Auto Spring, these leaf springs can feasibly support 950lbs more than stock.

Unfortunately, your only real option for a 2017-2019 Raptor Leaf Spring Upgrade would be a set of Deavers or similar complete leaf packs, though hopefully Deaver releases a mini-pack here for the newer Raptors soon.

Customer Question I have 2017 F150 FX4. I just purchased the Eibach complete pro-truck sport shock & strut kit with the pro-lift coil springs. Will I need to remove the factory 1.5” block for these leaf springs to make my truck stance level or replace with a smaller block?

Asked by: RyanClaypole - 5/24/2019
Customer Answer You likely wouldn't be level if you removed your rear block. The stock block is either 1.25" or 1.5" depending on submodel, so you'd essentially be at the same rear ride height. Your better bet would be the Halo Lifts 2" to 2.5" rear block kit, with the 2" block option getting you closest to "dead-level".

Customer Question I’m looking to stiffen up the rear of my 2018 F150, but only want 0-1in of life. Can the stock rear blocks be removed while installing these to reduce the amount of lift these springs normally provide? If so, what is the net lift when removing the stock blocks? Thanks!

Asked by: Josef - 4/22/2019
Customer Answer The stock block is either 1.25" tall, so you'll get about .25" of net lift going that route. If you're looking for 1" of lift and more control out of your truck's rear end, your better bet would be a 2.50" rear block kit and set of new rear shocks.

Customer Question Hello, I'm in a dilemma. I'm currently looking at a 5th wheel that has a hitch weight of 1300 lbs. My truck's GVWR (2016 F150 Supercrew, 157" WB, 3.5L Ecoboost) is 7050 lbs. Currently my max payload can only be 1880 lbs. With this 1300 lb hitch weight, this only allows me to have only 600 lbs left for me, my wife and two kids. What would this get me up to payload wise? And would I now be "legal" to drive this on the road? Thanks for the time!

Asked by: AJ - 3/13/2019
Customer Answer While these Add-a-Leafs add load capacity and definitely help you manage heavy loads and towing, you still cannot violate your truck's GVWR or GCWR due to legal and liability reasons if you get into an accident. More goes into a GVWR/GCWR calculation than just the truck's suspension, including the max load on the wheels and tires and how much load the brakes can handle. Unfortunately, that sticker on the door is pretty immutable in the eyes of both the law and insurance companies. Your better bet would be to look at a 5th wheel with less tongue weight.

Customer Question I have a 2019 F150 how thick is this spring? Will I need longer U-bolts?

Asked by: Tom - 3/6/2019
Customer Answer According to Auto Spring, the leafs are 3/8" thick. Longer U-bolts are not usually required, though there is some variation in stock U-bolt length over the F150's production run, so it's a good idea to check how much thread you have left on your stock U-bolts before install.

Customer Question I have a 6” lift currently installed on my 15’ F-150. I want to bump it up to 8” in the front and instead of changing my rear block to a larger rear block I want to keep the 5” rear block I have in there now and add this kit to it instead. Would this be applicable? Would I need to do anything else if this kit is applicable?

Asked by: Parker - 2/1/2019
Customer Answer As long as your have enough room on the rear block's U-bolts, there's no reason why you couldn't install this add-a-leaf kit. However, you'll need to double-check and make sure your rear shocks can handle the extra height and you may need a main driveshaft spacer (if your lift didn't already come with one) depending on how far your driveshaft yoke is outside of your transmission or transfer case.

Asked by: Chopps - 1/23/2019
Customer Answer That depends on which Bilstein shocks you're looking to use. The Bilstein 5100s are only rated to handle up to 1" of rear lift, and this add-a-leaf kit would push you beyond that. The Bilstein 5160s are rated for up to 2" of rear ride height and would work fine with this add-a-leaf kit.

Customer Question Hi, I installed the Readylift 69-2300 3.5" lift kit and 2" block in rear. Taht Block is 3" but Lift the truck only 2" when reemplaced stock. The question is: I want to go up an inch more and I think with this I will achieve it but I will have to buy some spacer for the Driveshaft or not?

Asked by: Angel Vazquez - 1/12/2019
Customer Answer You will likely need a driveshaft spacer, as well as new rear shocks, since this add-a-leaf kit would essentially put you at 3 to 3.25" of net lift after it settles, which is 4" lift kit territory. A 3" rear block should get you 1.5" to 1.75" inches of net lift depending on the size of your factory rear block (1.25" or 1.50" depending on year, submodel, and options). Frankly, I don't recommend going that high. Your better bet would be to get a smaller rear block and they possibly pair that with the add-a-leaf kit. Your best bet would be to call us directly at 623-44-5277 so we can get more specific about what you're trying to do.

Customer Question Trying to level my truck and looking at the rear options. Adding Bilstein 5100s to the front at 2.1". Stock rear block is 1 1/4". Im wondering about installing a AAL rather than bigger rear blocks. However, im looking for less rake than stock if any at all. Mainly concerned about the truck going nose high with a load in the back. So im wondering if this AAL can be installed without reinstalling the factory block? With the factory block plus this and the 2.1" gain in the front, it would be too much gain in the rear for my taste. But at least the AAL would better resist sagging under load even if it only gains 1/4"-1/2" of rear lift if the block is removed.

Asked by: Andy Davenport - 11/10/2018
Customer Answer Your real issue is that even with the Bilsteins set at 2.1" of ride height, you'll still have a smidge of front rake. Even if you remove the stock rear block and install the add-a-leaf/leaf pack directly on the axle, you'll still gain enough rear height to give your truck rake (especially since it takes a few thousand miles for the leafs to settle to their 1.5" ride height). If you want to be dead-level (or close to it) unloaded, but want to avoid going nose-high when loaded, your much better bet would probably be an air spring system of some sort.

Customer Question I have a 2015 F'150 157"WB 4x4 and recently installed the "2015-2018 F150 Stage 3 BOSS Trail Suspension Pack 2" kit on my truck to gain some extra ride height. Would I be able to install this AAL kit with the 3" blocks and shocks that were included on this kit without issue?

Asked by: Shelton - 11/7/2018
Customer Answer You would not be able to combine this add-a-leaf with a 3" rear shock and still use Halo Lift's rear shocks. They aren't long enough to handle that much ride height. Frankly, you'd have a ridiculous amount of rake with the combination and likely really weird handling, even if you did swap over to shocks meant for a 4" lift. The most rear lift that Halo Lift's BOSS 2.0 shocks can handle is 2" over stock, which means the most you could do is a 2" rear block and a 1.5" add-a-leaf kit. Your best bet would be to call us directly at 623-434-5277 so we can get more specific about what you're trying to do.

Customer Question What would be the pros and cons of doing the add a spring over a taller block?

Asked by: Logan Ridenour - 9/7/2018
Customer Answer Pros of an Add-a-Leaf over a block: Add-a-leafs increase load capacity (though still not your GVWR), aren't prone to axle wrap like larger blocks, and can be combined with larger blocks to fine-tune rear ride height if needed. Cons of an add-a-leaf over a rear block: stiffer rear ride quality (though that can mitigated with aftermarket shocks), more difficult installation, and they start out at about 2" of rear lift before settling to 1.5" which can give your truck a pretty stinkbug look until they're broken in.

Customer Answer Technically by the math, you'd need to be at 1.75" of leveling, but it's really tough to say since we both haven't done it before and add-a-leafs tend to start out a about 2" of ride height before settling down to roughly 1.5".

Customer Question I have a 2017 F150 crewcab 4x4 that I am looking to put the Eibach pro truck kit on(struts with the Eibach coil up front and the rear shocks that come with the kit) which I understand leaves you slightly nose high almost a quarter inch. Is there maybe a smaller rear block I can use in conjunction with an add a leaf to get the truck level with the front or maybe just slightly taller in the rear?(less than 1.5”) And a different question, will the Eibach rear shocks work with the stock rear block and an add a leaf? Thanks

Asked by: Andrew - 3/11/2018
Customer Answer Unfortunately, no one currently manufactures a sub 1.5" rear block for these trucks, so you'd en up with a noticeable amount of rake if you added an Add-a-Leaf kit to your truck's rear. Technically, the Eibach Pro-Truck rear shocks are only rated to handle 1" of rear lift over stock. However, a lot of folks have used both 3" rear blocks and 1.5" add-a-leaf kits without issues.

Customer Question I have a BDS 6" lift with the 5" rear block. BDS offers a 4" rear block. Would I see any benefit to the ride or payload capacity by switching to the 4" block and using this add a leaf to get back the height, basically replacing 1" of block height with 1.5" of spring height? Do you think there Would there be any issues using the U-Bolt that came with the lift?

Asked by: Paul - 2/23/2018
Customer Answer You still wouldn't be able to tow beyond your GVWR, so unless you're pushing your tongue weight close to its maximum, you likely wouldn't see too much of a benefit. That being said, the Auto Spring Kit will be more resistant to rear sag than just a larger block alone, so if you are seeing a decent amount of sag now, then doing the 4" block with the Auto Spring Kit may not be a terrible idea. The U-bolts that come with the 4" rear block should be adequate, though you will need to take care to tighten down the U-bolt nuts evenly to preserve as much thread as possible.

Customer Answer Auto Spring's Add-a-Leaf Kit is specific to the 2015-2017 F150s, and will fit your truck.

Customer Question what did this add a leaf do to the ride quality of your 3.5l ecoboost you installed it on... was it smoother?

Asked by: Matt - 6/6/2017
Customer Answer This Add-a-Leaf kit stiffened up our truck's ride quality by a bit, but that particular truck had a 6" lift with pretty "meh" shocks, and were trying to squeeze some extra height out of it. That being said, Add-a-Leaf Kits do tend to stiffen up your truck's ride by at least some extent, though using aftermarket shocks can help.

Customer Question Can I add this to my 2016 fx4 along with the BDS 4" or 6" lift kit?

Asked by: Jacob - 5/29/2017
Customer Answer You theoretically can, though you need to be careful to watch your brake lines, your e-Brake cable, and your rear shocks to make sure they're not being overly stretched.

Customer Question Hi I just bought a 2017 F150. The dealer added a level kit in the front (strut spacer) and it looks like it needs about an inch or so lift on the rear. Does this spring fit a 2017? If so how will it perform with the factory shocks?

Asked by: Dan - 5/24/2017
Customer Answer Auto Spring has confirmed fitment on the 2017 F150s. When used with the factory shocks, ride quality can stiffen up by at least some extent, though the effect is a lot less noticeable when using aftermarket shocks.

Customer Question Can lift my truck 4" and still put these leaf springs in?

Asked by: Ernie - 2/12/2017
Customer Answer It kind of depends on what size rear block is included, since taking the rear too high may require a different a different brake cable drop bracket. However, you could technically do it if you wanted to gain back some rake and cargo capacity for towing/hauling.

Customer Question Hi, I am planning on purchasing a 2017 f150 soon. I would like to have it level with the rancho quicklifts in the front. Can these be ran with the factory 1.5 blocks removed on the rear so that I would still maintain a level stance if towing? Thanks

Asked by: Mark - 2/9/2017
Customer Answer You theoretically could, though you probably want to check the amount of thread on your factory U-bolts, since you'll be using them farther up.

Customer Question Will I need to replace my factory shocks with longer travel shocks with the addition of the add-a-leaf kit?

Asked by: OakTree20 - 10/4/2016
Customer Answer You technically don't have to. The factory shocks can handle the additional ride height. That being said, ride quality can stiffen up a bit when you use an Add-a-Leaf kit with the stock shocks.

Customer Question I have a 2017 F150 Supercab FX4 on order, and I am looking to do a lift/level with an add-a-leaf in the rear. Will this kit work with Fox 2.0 rear shocks and the 1.5" block that comes with the truck? I know the Fox shocks state that they can accommodate 1-1.5 inches of rear lift, just want to be sure they will work with these. Thank you.

Asked by: Ben - 9/14/2016
Customer Answer Yep. The Fox 2.0s will work in conjunction with basic 1.5" Add-a-Leaf Kits. That being said, we don't have official confirmation that these Add-a-Leafs will fit a 2017 F150 as of yet. That being said, we're about 90% sure that their fitment will carry over, but we would like to be sure.

Customer Question Will these work with the Boss Ultimate kit since the Boss can only accommodate 1.5" of lift and these can be between 1.5 and 2"? if not, what do you recommend for rear shocks?

Asked by: James - 9/7/2016
Customer Answer The F150Lifts Boss Rear Shocks can handle this Add-a-Leaf kit without issues.

Customer Question If using an Add a Leaf, are there any recommendations to maintain the factory pinion angle, or is a shim included to remedy this?

Asked by: Joe D - 9/6/2016
Customer Answer While pinion angle can be thrown off to some degree, at 1.5" of lift, it's not generally enough to cause issues or driveline vibrations and shims are not included as standard.

Customer Question What's the average hight these are getting? And is there an option to were I can only get one inch? Thanks!!

Asked by: Mike k - 8/21/2016
Customer Answer The Add-a-Leafs generally start out at a 2" ride height gain that settles down to roughly 1.5" after they've been broken in. Unfortunately, Auto Spring does not currently offer an add-a-leaf kit with less lift.

Customer Question if adding the leaf kit do I need to use longer ubolt on a 2015 f150 lariat?

Asked by: dan - 6/12/2016
Customer Answer Nope. You should be good. Add-a-Leaf kits typically do not require longer U-bolts when used with the factory rear block.

Customer Question Would getting the rear add a leaf require something for a stock front end? I.e. Lift or level?

Asked by: Ian - 6/5/2016
Customer Answer You wouldn't strictly need to, but putting an Add-a-Leaf Kit on your truck will increase your truck's front rake significantly, and you may not appreciate the stance. Still, you don't technically need to add any front lift in order for the Add-a-Leaf Kit to fit an function on your truck.

Customer Question Can I run these with fabtech 6in lift blocks and still grab another 1.5-2in of lift?

Asked by: Austin - 1/27/2016
Customer Answer You technically can, though you're going to need to be fairly careful and make sure your e-brake cable and brake lines aren't overly stretched or stressed, and if they are, you may need to get them extended. Also, you may need to add a driveshaft spacer or get a larger driveshaft spacer, as adding an Add-a-Leaf kit to a lift will generally cause your truck's driveshaft to slip from the yoke farther than just the lift kit alone. I would strongly recommend getting the driveshaft spacer a head of time.
