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.

    Tuff Country cast iron rear block kits are sold in pairs and include u-bolts with hardware. They are designed for vehicles with leaf springs above the rear axle.
