KSP 2" Rear Lift Block Set for F250 F350 Super Duty Trucks 1999-2024, 2in Rear Suspension Lift Kits Include 2pcs lift blocks and 4pcs U-bolts Compatible with F-250 F-350 2WD 4WD Heavy Duty Pickup

I could not believe the quality of the product. The nuts are bigger than factory and the blocks fit perfectly and are reinforced. I did not take the wheels off just lifting one side of the receiver hitch in a single lift while using a jack stand and jack. I just lifted safely, kept my head out of the wheel well, blocks fit in easily just placing in place releasing a little tension and shuffling the wheel around. Stay safe don't pinch your hands. Had to reach in with a grinder with a cut off wheel after to cut u bolt ends for torque to spec. Wondered about double nutting but didn't. It's an option with hardware suppliers now days. Good luck! It's amazing the quality of non name brand now days.

Good kit. I bought the kit for the ubolts, it was the only way I could get any set the next day. They’re tough and those blocks are too. Although the bolts are a tad wide for my 18 F250 they work good. They spec the bolts to 110ft# but factory is 195ft#. Mine weren’t acting right, ongoing issue, I hit them to 230ft# and they’re holding solid.

Leveling my truck in the front.Great for the money. Works great!! Easy installation

If you have done any work with lifts you probably already know u bolts are generally cut to fit. Seems like a lot of reviews on here mention the bolts are too long but don't know they need to cut off the excess. Either way the problem I faced was that the threads on the u bolts were about 1/8 of an inch not deep enough preventing the supplied nut from clamping down on the provided washer. I worked around this by using the factory thick washer in conjunction with the provided washer to get a more correct thread engagement. I also marked an index line so I could verify the nuts weren't twisting off after driving.U bolt issue aside this kit allowed me to remove the stupid 4" blocks from the rear of my truck and replace them with an appropriate oem size block equivalent for my F250.

Worked fine for my 2019 F250. Needed a spring coil compressor. You can borrow them at Advanced auto. I did it myself and I’m pretty handy but it took all day. I’m happy with it.

The Spring perch Block itself is fine, much nicer than the top raise system and less tension on the brake hose. However, the shock extension block doesn't fit and needs to be pretty extensively custom ground down to fit and will still give you some lip.

Same size as the stock block under an F350. Not worth the purchase.
