F100, F150, Ranger Ford Block & U-Bolt Kits

We offer a large selection of rear block and u-bolt kits for Ford trucks 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.

    Skyjacker Rear Block Kits include a pair of cast iron blocks with 4 u-bolts, Nylon insert lock nuts and washers. Skyjacker blocks are high quality ductile iron (not gray iron) tapered and are 1-piece construction with axle pins built-in.
