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

For the price you can't
For the price you can't beat this kit, u bolts alone are usually about 35-40 dollars so this kit comes with everything for under 60 dollars.
