The Skyjacker C160AK8 6-Inch Suspension Lift Kit for 1988-1991 GMC Suburban 1/2 Ton 4WD models is engineered to provide increased ground clearance, improved off-road capability, and the aggressive stance that complements the full-size Suburban platform. Built around heavy-duty replacement front leaf springs and premium suspension components, this complete system delivers 6 inches of suspension lift while providing clearance for up to 37x12.50 tires. Multiple Skyjacker shock options allow the suspension to be configured for a variety of driving styles, from comfortable highway cruising to demanding off-road adventures.

The kit includes heavy-duty replacement front leaf springs, rear lift blocks, front and rear U-bolt kits, a front leaf spring bushing kit, and brake line brackets to properly accommodate the increased ride height. Designed as a bolt-on suspension system, the C160AK8 installs without cutting or welding, making it an excellent upgrade for restoring suspension performance while significantly increasing ground clearance and vehicle capability.

Choose the suspension performance that best fits the application with Skyjacker Black MAX shocks for dependable daily driving, Hydro 7000 hydraulic shocks for smooth ride quality, Nitro 8000 nitrogen-charged shocks for enhanced control and stability, or M95 monotube shocks for consistent damping performance and improved heat dissipation. Whether tackling rugged trails or giving a classic GMC Suburban a commanding lifted appearance, the C160AK8 provides the strength, reliability, and performance expected from a premium Skyjacker suspension system.
