Superlift 69-72 Chevy 1/2 and 3/4 Ton Pickup 4WD 4in Rear Block Kit

These cast iron rear blocks from Superlift are designed to lift the rear of your 1969-1972 Chevy or GMC 1/2 or 3/4 ton 4WD pickup by 4 inches. This is a popular choice for leveling out the stance of a truck that's already been lifted in the front, or to make room for larger tires. The kit includes two solid cast iron blocks, four heavy-duty U-bolts, and all the necessary nuts and washers to get the job done.

Cast iron is a strong material that holds up well under the stresses of lifting and supporting the rear axle. Superlift has been making suspension components for trucks since 1975, and they focus on making parts that perform well both on and off-road. This kit is a straightforward way to add lift to the rear of your classic GM truck.

When installing this kit, you'll be working with the rear leaf springs. Make sure you have the proper tools to safely support the vehicle and remove the old U-bolts. This kit is designed to fit a range of classic GM trucks, including the Chevrolet Blazer, K10 Pickup, K20 Pickup, GMC Jimmy, K15/K1500 Pickup, and K25/K2500 Pickup from 1969 to 1972.
