Straight Axle Pickup Chevy, GMC Block & U-Bolt Kits

We offer a large selection of rear block and u-bolt kits for Chevy and GMC truck, SUV and SUT with rear leaf spring suspension. Rear lift block kits include a pair of rear blocks with u-bolts and hardware. They are a simple way to raise the rear of your vehicle if your leaf springs have started to sag. Unlike an add-a-leaf, rear lift blocks will not adversely affect your ride quality.

If you use your vehicle for hauling or towing, the addition of a block kit will maintain the factory rake of your vehicle. If you don't find the combination you're looking for, blocks and u-bolts are sold individually for a custom application.

All rear block kits listed are designed for the rear of your vehicle only. The leaf springs must be above the axle.

    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.
