6" 1973-1986 GMC Suburban 3/4 ton 4WD Lift Kit (w/rear leaf springs) by Skyjacker

The Skyjacker C160BKSD 6-Inch Suspension Lift Kit for 1973-1986 GMC Suburban 3/4-Ton 4WD models is designed to provide increased ground clearance, improved suspension capability, and a commanding lifted stance for classic full-size Suburbans. Engineered specifically for vehicles equipped with 56-inch rear leaf springs, this complete suspension system replaces the front and rear springs to achieve 6 inches of lift while providing clearance for up to 37x12.50 tires. Multiple Skyjacker shock options allow the suspension to be configured around the desired ride and performance characteristics.

The C160BKSD includes replacement front and rear leaf springs, front and rear U-bolt kits, a leaf spring bushing kit, and brake line brackets to accommodate the increased ride height. Using replacement springs at both ends provides a complete suspension-based lift rather than relying on rear lift blocks, while the included mounting components help ensure a secure, comprehensive installation. The system is designed to install without cutting or welding, making it a straightforward option for upgrading the stance and suspension of a classic 3/4-ton Suburban.

Available shock configurations include Skyjacker Black MAX shocks for dependable everyday performance, Hydro 7000 hydraulic shocks for smooth and controlled damping, Nitro 8000 nitrogen-charged shocks for increased control, and M95 monotube shocks for enhanced damping consistency and heat management. Combined with the full replacement spring system, the C160BKSD provides the components needed to build a capable 6-inch lifted Chevrolet Suburban for street or off-road use.
