Superlift 73-91 Chevy K20/GMC K25 4WD 6in Lift Kit Rear Block Kit w/ Superlift Shocks

If you're looking to give your classic Chevy K20 or GMC K25 pickup or Suburban a significant lift for improved off-road capability and the ability to fit larger tires, this 6-inch rear block kit with Superlift shocks is a solid option. This kit is designed to work with solid axle 4WD models from 1973 through 1991, offering a substantial increase in ride height. It's a common scenario for owners wanting to tackle rougher terrain or simply achieve that aggressive stance that these trucks are known for.

Superlift has been in the suspension game since 1975, and this kit reflects that experience. The rear block kit includes sturdy blocks that bolt between your leaf springs and the axle, effectively raising the rear of your truck. Paired with Superlift's own shocks, this kit aims to provide a balanced ride, considering that most of these trucks spend a good amount of time on the road. The shocks are chosen to complement the lift height, helping to maintain reasonable on-road manners while still performing when you head off the beaten path. This is a considerable investment, and Superlift focuses on creating products that perform well for the long haul.

When undertaking a lift project of this magnitude, it's always a good idea to review the manufacturer's installation instructions thoroughly. Ensure you have the necessary tools and potentially an extra set of hands, as working with suspension components can be challenging. This kit is designed to fit a wide range of 3/4 ton 4WD trucks and Suburbans from the mid-70s to the early 90s, including popular models like the 1973-1986 Chevrolet K20 Suburban and the 1979-1986 GMC K2500.
