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
Easy install. All hardware inluded at a great price. Couldn't be happier.

Perfect fit.
Got this lift kit for my 1975 k-20 suburban 2 wheel drive. I had called about them and the company couldn’t confirm that they would work on a two wheel drive, they only sold them for a 4 wheel drive. Went ahead and ordered them anyway and they worked out perfectly the u-bolts were all the right size the block fit exactly how and where it was supposed to. Nothing seems to have changed as far as ...handling is concerned, so it didn’t throw anything else off. Looks great, the 3” lift is the perfect height to give the suburban a more level look. Stock they always look like their sagging a bit in the back, this took care of that perfectly and gives me quite a bit more clearance in the back. I would definitely recommend anybody with an older square body suburban get this lift kit.Read More

It would be great if you offered an extended break line from the frame to the axle

The u-bolts were too long so i had to spend an extra $30 for u-bolts that fit
