F250, F350 Ford Block & U-Bolt Kits

The Ford F250 and F350 are well-recognized working trucks. This can sometimes mean that rear leaf springs prematurely lose height due to heavy usage. Put your truck back to a more level or stock stance with one of the many Ford blocks and U-bolt kit options available here.

Superlift

The Superlift rear block kits include a pair of cast iron blocks along with u-bolts, locking nuts and washers.
