Straight Axle Pickup Chevy, GMC Block & U-Bolt Kits
The straight axle pickup with rear leaf springs will often need some rear spring lift after usage and time have taken their toll. We offer a wide array of rear block and u-bolt combinations for these Chevy and GMC models. Custom combinations of blocks and u-bolts are available separately if you don't find what you're looking for here.
The Superlift rear block kits include a pair of cast iron blocks along with u-bolts, locking nuts and washers.
