Easier Towing and Raised Ride Height

Strong, high-quality rear block kits for your F150 are not easy to come by, but our friends over at Ready Lift have you covered with this 1.5" rear lift block kit. These blocks are a great way to get some extra clearance, get back at least some of that rear rake when you grab an F150 leveling kit, or to help you tow and keep a more controllable ride. These blocks easily install on top of your stock leaf springs and are strong enough to give you years of reliable use for just about any application.

Extremely Strong, High-Quality Block Kit

Each of these high-quality Ready Lift rear block kits come with two 1.5" cast iron blocks with a black E-Coat finish that keeps them protected from corrosion, heavy-duty E-Coated U-bolts, and other hardware. The kit has an OE-style design with perfect bump stop landings and pinion angles to keep your smooth factory ride while helping you tow.

This kit only fits RWD F150s.

My 2015 Platinum 4wd came with 1.25" block. Running Fox 2.0 up front and rear. Just confirming this could replace my OEM block for a slight boost in the rear?

Asked by: Dean Ayala - 3/10/2022

You feasibly could. I don't think that .25" is going to make much of a difference, but the Fox 2.0s can handle it and this kit will technically fit on a 4WD truck.

I recently installed a 2.5" Falcon tow/haul level kit on my '21 XLT RWD. Now it actually looks like the rear has a small amount of squat instead of being right on level. Is this normal considering I didn't add any blocks to the rear? Considering adding a set of these to solve the visual (rides just fine), but don't want to recreate the rake that had me install the level kit in the first place.

Asked by: QGreene - 8/25/2021

This rear block kit is not guaranteed to fit 2021 F150s, and Falcon has not outright confirmed fitment of their kit on the 2021 F150s as of yer either. In general, it takes about 2.5" of leveling to get these trucks to a "dead-level" stance, though that does depend somewhat on the condition of the stock suspension. Considering you have a newer truck, it may just be a matter of getting some more miles on your vehicle to get the front suspension to settle in. Hopefully, we'll have fitment confirmations for 1.5" rear blocks extremely soon.

Can i install these on my 2wd without having to replace my rear shocks. My turck only has 20k miles on it so I don't really want to invest in new longer shocks right now.

Asked by: Sarmad - 3/24/2020

The stock shocks can handle the additional height, though they aren't super-happy about doing it. As long as you're not off-road too often and really articulating your rear suspension on the regular, your stock shocks should be fine.

Adding these to 2015 f150 Rwd trying to figure out which bistein 5100 to go with the rwd ones or 4wd Bilstein recommended 5160 but out of price range

Asked by: Travis - 3/14/2020

Since a 1.5" rear block on an RWD F150 is essentially the same height as a stock 4WD F150, you can use the 5100s for 4WD F150s and be in an optimal travel range with no issues.

Will I have to change anything else with the rear suspension to add these? Will they work with my factory shocks, etc?

Asked by: Brian - 4/29/2019

These blocks will technically work with the stock shocks, but we do recommend jumping up to shocks meant for 4WD trucks so that you're in a more optimal range of travel, especially if you have a lot of miles on your factory shocks.

Can you use these rear blocks with the shocks in the 2015 f150 2WD ICON Stage 1 0-3" Suspension System?

Asked by: J.C. - 10/30/2018

Yep. The ICON 2.0 rear shocks included in their F150 RWD can handle up to 1" of rear lift on 4WD F150s, and you'd be able to use this block on an RWD F150 without issues.

I have rwd 2018 f150 and the rake difference is 1in and im planning to go with a 2.5in leveling kit in the front and this kit would get me dead on even would I need shocks with the rear blocks?

Asked by: gus - 7/17/2018

In general, it takes a 2.5" leveling kit on its own to give the 2015-2018 F150s a "dead-level" stance. Your best bet would be to get the leveling kit and see where you're at before you invest in a rear block at all. Technically, aftermarket rear shocks aren't required for a 1.5" rear block, but we recommend getting a set due to the factory shocks not having the best ride at factory ride height, much less at a taller height.

Would this block make a 2WD 2018 F-150 the same rear stock height of a 4WD? Secondly, if adding a 1.5” rear block, would Bilstein 5100’s for 2WD at 1.75” still negate some of the rake? I’ve heard setting Bilstein 5100’s is a very rough ride so 1.75” is my ceiling.

Asked by: John Smith - 12/2/2017

You'd be very close to right at a 4WD F150's rear ride height, since those trucks could come with either a 1.50" or 1.25" block depending on package options. The Bilstein 5100s at 1.75" or height would get rid of some of your rake, but you'd still have a pretty considerable amount. You have to keep in mind that 2.5" of leveling tends to get these trucks "dead-level", and you want to add 1.50" onto that. Your better bet would be to do the 4WD Bilstein Kit so that you both squeeze some extra ride height out of the front, while getting shocks that will be in a more optimal operating range when used with a 1.50" rear block.

I just bought bilstein 5100 front and rear would the 1.5in or 2in rear block work with them or do I need longer shocks?

Asked by: Dakota Peters - 8/21/2017

The Bilstein 5100s should be able to handle a 1.5" rear block without issues. If you want to jump up to a 2" rear block, then we'd suggest getting the 5100s meant for a 4WD F150s, as they're longer than the RWD versions and will be in a more optimum operating range.

Will this work as a replacement for stock 4x4 block? Looking to go from 3" block to stock ride height. Thanks!

Asked by: Nick - 8/14/2017

Yep. It's essentially the same height as a stock FX4 rear block, and should work how you need it.

Would this work on a 4x4? I wouldn't think that the rear blocks and u bolts would be any different just cause its only 2x4. 3" is too much thats why I am after the 1 1/2" rear blocks. Thank you

Asked by: J.T. - 9/1/2014

Here's the thing and why this is a little confusing. All 4WD F150s, from the factory, come with 1-1/2" rear blocks as stock. When you get a 3" rear block, you remove your stock block which drops the truck's rear down by 1-1/2". Then you add in the 3" block. You're still only adding 1/2" of extra height, which is why 3" blocks are the go-to for taller 3" front coilovers and the like. If you still have questions, give us a call directly at 1-877-578-2433.
