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

Great value!
Super lift sells the entire kit for less money than other company’s want just for the blocks. Can’t beat the price and reputation.

Lift blocks
I am happy with it but the nuts are the wrong size and would not fit the u bolts provided. Thankfully, I was able to use the factory bolts otherwise I would have had a major project. Other than that, the blocks seemed a little skinny but I’m am satisfied otherwise.
