Tuff Country 73-87 Chevy Truck 3/4 Ton 4wd 4in Rear Block & U-Bolt Kit

This Tuff Country rear block and u-bolt kit is a straightforward way to lift the rear of your 1973-1991 Chevrolet or GMC 3/4 ton 4-wheel drive truck. It's designed to add 4 inches of lift by placing cast iron blocks between your truck's axle and leaf springs. This is a popular method for leveling out the stance of a lifted front end or making room for larger tires.

The kit includes durable cast iron lift blocks and extended, zinc-plated u-bolts that are custom-fit for the specific applications listed. The zinc plating on the u-bolts helps resist corrosion, keeping them looking good and functioning properly over time. This kit focuses solely on the rear axle, so you'll need to ensure any front-end lift components are compatible and provide the desired overall stance.
