Drop-In System that Helps Level out up to 6,000lbs of Load

Preventing sag in your F150's rear end when your bed is loaded down can be a pain, especially if your truck is already leveled up front to squeeze on bigger tires. If you want avoid having to go with an expensive air spring system, then you should check out the Timbren Suspension Enhancement System (SES). The SES consists of a pair of high-strength extended Aeon® bump stop rubber springs that install between your 2015-2023 F150's frame and rear axle and provide you with up to 6,000lbs of load leveling to prevent rear sag and improve your F150's loaded handling and stability. The SES is extremely easy to install, with the Aeon springs dropping into place of your F150's factory bump stop and the lower bracket bolting around your F150's axle with included U-bolts.

Specialized Rubber Springs with Heavy-Duty Steel Mounting Plate

The Timbren 6,000lb Suspension Enhancement System is built around a pair of Timbren's Aeon® rubber springs and come with all the hardware you need to get them installed on your truck. The Aeon® springs are made out of specialized rubber compound that actually gives them a progressive spring rate which helps them keep your loaded ride leveled without overly compromising your F150's ride quality. The rubber material is nearly indestructible and resistant to corrosion and wear. The lower brackets included in each kit are made out of laser-cut steel that's then topped off with a powder coat finish to prevent corrosion. Each SES kit comes with installation hardware and instructions. Timbren even backs the system with a limited lifetime warranty.

2018 Ford F 150 XL STX

Had these on my 2004 Toyota Tacoma, removed all squat when towing or loaded, without affecting the unloaded ride, and without the complexity of an air bag system. A must have upgrade for my new F 150.

Purchased these to help prevent excessive sag in the rear end without the hassle of airbags. While air bags might give a little more ride height, these work great and were super easy to install. Had them both installed in 30 min. Would highly recommend for ease of install and what they offer.

I wanted to try the Timbren kit on my truck as I have had a full airbag kit in the past and figured this install would be quicker and easier. I can tell you I wasn't disappointing with the results. I pull a 26ft toy hauler and fully loaded its near 10k lbs, and prior to the Timbren kit my truck had more than 4" of squat and pretty much sat on the bump stops. WIth this kit installed it only squats 2.5" and more importantly when going down the road the truck has more stability. A bonus to this is when Im unloaded I can offroad the truck without feeling the Timbrens hitting to the point that it would effect my King suspension in any way. Would definitely recommend the Timbrens to anyone that wants a simple install with great results.

DO NOT BUY! Short story: Rides way too stiff under load, still sags, and causes the front end to dip because there is only 1” of suspension travel. Makes the whole truck bounce down the highway. My truck rode like a brick wagon. This is no exaggeration. Long story: Out of the box the paint was already flaking off and chipped. But I installed anyway a day before my trip. My truck only has 50k miles, and I was towing a 16’ double axle, enclosed, all aluminum trailer with 3 motorcycles in it. Just going around town seemed fine, but on the highway there were hour long periods of minor bumps that would not normally be felt, that were literally causing the whole truck to bounce down the road like an empty dump truck. Horrible experience for a 14 hour drive. I’ve towed this same trailer set up before without this product, and it sagged a lot, but still rode smooth. This product only take away about half of the sag, and rode like garbage. Do yourself and your wallet a favor and buy some air bags or a roadmaster system. I’m now stuck with a $230 paper weight.

I have a 2019 F-150 ecoboost 3.5 engine . i am towing a 10,500+ travel trailer. my question is . when i tow the trailer on a road or highway and go over a bump or a dip in the road the back end of the truck and front of the trailer continue to bunch up and down will this help stop or minimize this? and will my truck still be level when not towing? thank you

Asked by: Kevin - 8/24/2020

The Timbren SES system may help. The real issue is that instability when towing that heavy can have a bunch of different causes, so you should probably at least double-check some things before you start throwing money (and parts) at the problem: 1). Make sure your trailer weight distribution isn't biased toward the rear axles. You're pushing your truck's GVWR/GCWR with that trailer, and I know it's probably not 100% possibly to get more weight on the tongue than over the trailer axles, but it's at least something to look into. 2). Look into a weight distribution hitch or adjusting your current WD Hitch's settings. 3). Consider looking into aftermarket rear shocks, as they can help settle your axle back down after bumps and dips in the road.

I'm interested reducing squatting of my f150 with however I have built the truck around going offroad will these stops hinder axle articulation significantly?

Asked by: tommy kemp - 9/23/2019

They'll really only hurt up-travel, and even then, it will likely only be slightly more than the factory bump stops. If you want to keep maximum travel in your rear suspension, your better bet would likely be an add-a-leaf kit or even entirely new leaf springs.

I have a 2 inch leveling kit on the front of my 2017 F150 Screw. Factory on the rear. Will this work to help prevent squat when towing?

Asked by: Andrew - 7/11/2020

They'll help reduce the amount of squat, though you will still get some, especially if you're pushing your max payload or GVWR/GCWR.

Will these work on a 2016 f150 with a 2 inch lift on rear? Thanks

Asked by: Derek - 2/18/2019

You can still install the kit, though it will lose some of its effectiveness due to the fact that the Aeon springs are designed for F150s at stock ride heights and will need to travel an extra couple of inches to contact the striker plate on the axle. They'll still work, but you way get some sag or squat depending on what your front suspension setup/ride height happen to be.

Will these work with the Auto Spring Add A Leaf Kit?

Asked by: Shane - 7/18/2019

They'll fit just fine in conjunction with an add-a-leaf kit. However, it's tough to say how much benefit the Timbrens provide you after the add-a-leaf kit, given how much support the AALs will end up providing. Still, there's no reason why you couldn't do it.

Asked by: Mike - 8/28/2020

Yep. The Timbrens will work with Fox 2.5s without issues.

How well do the timbren 6,000lb SES work compared to standard airlift 5,000lb air bags? I haven't seen much for reviews

Asked by: Kyle - 10/3/2018

Unfortunately, we have not tried the Timbren SES kits on any of our trucks as of yet. We're hoping to rectify that soon. In theory, the SES kit will preserve more of your truck's unloaded ride quality, though they aren't as supportive as a set of Air Springs.

Will these work with the falcon terraflex towing shocks in the leveling kit setup?

Asked by: Kyle - 3/21/2019

They will not. The TeraFlex system comes with bump stop extensions and striker plate that interfere with the Timbren install. Your better bet if you're doing a lot of towing would be to use the Timbren Kit in conjunction with basically any other rear shock on the market.
