Superlift 73-91 Chevy K10/GMC K15 4WD 6in Lift Kit Rear Block Kit w/ Superlift Shocks

This Superlift rear block kit, designed for 1973-1991 Chevrolet and GMC 4WD trucks and SUVs with solid front axles, uses 6-inch tall blocks to raise the rear of your vehicle. This lift height is often paired with a front lift to achieve a level stance or a slight rake, which can be beneficial for carrying loads or towing. The kit includes Superlift shocks specifically chosen to complement the lift height and provide a comfortable ride on and off-road.

The blocks themselves are constructed from durable steel, built to withstand the stresses of lifting and driving. They install between the rear axle and the leaf springs, a common method for adding lift without altering the spring rate significantly. This approach helps maintain a predictable ride quality, especially since Superlift designs their kits with on-road manners in mind, even though they perform well off-road. The included shocks are tuned to work with the increased suspension travel and geometry created by the lift blocks, aiming for a balanced feel.

This kit is a solid option for owners looking to achieve a 6-inch lift on their classic Chevy or GMC pickup, Blazer, Jimmy, or Suburban. It's important to note that a 6-inch lift typically requires other components, such as front lift components and potentially driveshaft modifications, to complete the conversion. Always consult the manufacturer's installation guide for a full list of recommended parts and procedures.
