Superlift rear block kits help distribute the weight of your cargo and improve the towing performance of your truck. They'll also give your rear a little lift to bring it back to the proper ride height.
Superlift's block kits include two cast iron lift blocks and four U-bolts with factory type Hi-nuts and flat washers. The blocks are cast from Class 30 Gray Iron, the same material used by vehicle manufacturers for their spacer blocks. Our U-bolts are manufactured from low allow, high strength steel. The anti-corrosion finish is either Zinc or E-coat
30 min install. Everything went according to plan.

Your blocks were tapered vs the stock ones being flat. Tapered blocks were not part of the product d...escription. It threw the pinion angle to far out of spec and created a vibration so I was unable to use the blocks. Additionally, the U-bolts you sent me were 18” long so those were completely useless. Finally, your return process was too much of a pain in the ass so I’m just going to eat the 80 dollars I spent on this garbage. No I will not recommend this product and you feel the need to discuss further, you can reach me at+18059158738Read More
