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.

    Rough Country rear block kits contain a pair of lifted blocks and 4 u-bolts with nuts and washers. These are the same blocks used with Rough Country lift kits.
