Blocks

Rear lift blocks are sold in pairs. 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.

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