KSP 2" Lift Block for F150 2004-2020, 2inch Rear Leveling Lift Kit for Ford F150 with Extra Long Square U Bolts and Cross Block, Ford Rear Lift Kit Replace for Factory Blocks

These rear blocks are great. I haven’t had them long so I can’t speak for longevity but quality seems very good. Added bracing which is nice. Took literally less the 20 minutes to install. And at the end of the day my 2” blocks got me a full 2” in hight.

Only a 30 minute install. Good quality. Truck looks great

Installed 2 inch level in the front of f250 truck but it seemed to have a little sag in the back. This 2 inch level for the back gave me the height and look I wanted.

I assumed I knew what I was doing and I goofed it twice. As a first time truck owner and first time block installer it seemed easy as pie. Here are a couple things I learned.1- Just lift the leaf spring close to the blocks as they are.2- They can be installed backwards so be sure the flat part is on the bottom and the tapered side is on top. One side will be taller than the other. Put the thicc side toward the tailgate and the thinner side toward the engine. They aren’t specifically driver/passenger side so they can’t be backwards in that respect.3- Tighten those bolts like you’re taking your anger out on your cat that can’t stop throwing up.I am currently facing the reality that I probably need to uninstall the stock blocks as well. I have them sitting on top of each other because I love the height, however from like 55mph and up (and ONLY coasting/braking which is strange) there’s a whirring/vibration noice that hummmms throughout the cabin. It’s very annoying and I think the problem is that I have both blocks installed. I just don’t want to take them out :(Overall great product, does the job. 4 stars because no installation guide and ultimately I have a buzzing noise (that probably could have been avoided if I was taught how to install them with an owners manual).

10/10 recommend

These stacked on top of factory 250 blocks, and the new ubolts were the perfect length. 2 floor jacks and 30 minutes. This kit was a must after installing a leveling kit up front. Hardware was better than any RCX kit I've had the pleasure of working with!

The install was rather quick and easy, but like others have pointed out the U Bolts are way too long and need to be cut. I used a grinder with a cut-off wheel and it only took a few minutes to cut all ends off. I gave it three stars because the ends of 2 U Bolts (one on either side) was almost touching the lower hardware for my rear shocks. This made it impossible to torque down without cutting the bolts and also would have caused damaged to the shocks hardware.

Great bang for your buck to stop your truck from squatting.
