3" thickness

PRODUCT IS AS DESCRIBED.

This kit fit my 2010 f150 super crew 4x4 perfectly. To be honest I only used the bolts. I did slip the blocks in to check fit. They were perfect. Clearly well made, and the quality shows.

Easy to install worked as they should

I installed these on my 2016 f150 4x4 super crew.The factory blocks on that model truck are 1 1/4 inch so these blocks should lift the rear 3/4 inch. That is exactly what it did for my truck.I put bilstein 6112 lift shocks on the front of my truck at the highest setting. With a canopy on back my truck sat exactly level or even 1/4 inch nose high. These blocks gave me 1/2 to 3/4 inch rake again. It looks perfect.Install went really smooth. I did one side at a time. I loosened the nuts on the u-bolts. I put a jack under the leaf spring, just in front of the axle and jacked the spring up enough to slip out the factory block and slip in the new block. I lowered the spring onto the new block. Then I installed the new u-bolts and cut off the extra length with a cutting wheel on an angle grinder. The whole process took about 1.5 hours, by myself.No difference at all in ride quality. But I have bilstein 5100 shocks in the rear also.The first picture is in my driveway, before the rear blocks. The second picture is the test drive, after the rear blocks

Love it.

Had a problem with one of my U bolts during install. The trick is you can't "Pre cut" the U bolts, as some of the nuts will not take to the threads so well. Emailed the company and in less than 48 hours I had a new kit. So be sure to wait to cut the excess off until after you install them. Otherwise the install wasn't too hard.

I got these to bring the rear of my truck up to level it out after getting 3 inches of lift on the front of my truck. I’m very happy with it. It was easy to install for sure. Buddy and I got it done in about 40 minutes total including break time. It was a cinch! Very happy with the end result.

worked well and did the job I needed
