Superlift 73-91 Chevy K10/GMC K15 4WD 8in Lift Kit Rear Block Kit w/ Superlift Shocks

This Superlift K423 kit is designed to lift the rear of your 1973-1991 4WD Chevrolet or GMC pickup, Blazer, Jimmy, or Suburban by 8 inches. What you get in this specific package is a set of rear lift blocks, which are solid pieces of steel that go between your axle and leaf springs to increase ride height, along with a pair of Superlift shocks specifically chosen to work with this lift height. This is a rear-only kit, so if you're looking to lift the front of your vehicle, you'll need to find a separate front lift system. This kit is a popular choice for those looking to achieve a more aggressive stance and gain clearance for larger tires on their classic Chevy or GMC truck.

Superlift has been in the suspension game since 1975, and they build their kits with the understanding that most trucks spend their time on the road. That means you get a lift that performs well off-road but also handles comfortably during your daily commute. The blocks themselves are made from strong steel, ready to handle the stresses of off-road use and the weight of your truck. The included Superlift shocks are tuned to complement the lift height, helping to maintain a smooth ride and proper suspension travel. This kit is a significant upgrade for your vehicle's suspension, allowing for a much more imposing look and the capability to fit larger tires, which is often a primary goal for owners of these classic 4x4s.

When installing a lift kit like this, it's important to remember that it's a major modification. You'll want to ensure all hardware is properly torqued and that you follow the manufacturer's installation instructions closely. Because this kit focuses on the rear, you'll need to pair it with a compatible front lift system to achieve an even 8-inch lift all around. This setup is ideal for owners who want to give their classic truck a serious lift for both looks and function.
