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.

5" rear lift block
My leaf springs are 3" wide these block are 2 1/4", u-bolts are apparently sized to stack blocks, which I would never do, I may not have read description thoroughly. I did not use any part of this kit.
