8" 1988-1991 GMC Suburban 3/4 ton 4WD Lift Kit by Skyjacker

The Skyjacker C180BK8 8-Inch Suspension Lift Kit for 1988-1991 GMC 3/4-Ton Suburban 4WD models provides a substantial increase in ride height for improved ground clearance, larger tire clearance, and a more aggressive stance. This suspension system combines Skyjacker Softride front leaf springs with rear lift blocks and add-a-leafs to achieve the increased height while retaining the proven leaf-spring suspension layout of the heavy-duty Suburban. The complete front-to-rear configuration provides the clearance and suspension height needed for larger tires and more capable street and off-road builds.

Skyjacker Softride front leaf springs replace the factory front springs and provide the majority of the increased front ride height. Their design lets the suspension maintain useful movement and articulation while supporting the extra height required for an 8-inch lift. At the rear, heavy-duty lift blocks work together with Softride add-a-leafs to raise the rear suspension and complement the taller front springs. This combination provides a balanced lifted stance without requiring a complete rear spring pack replacement.

The C180BK8 is available without shocks or can be paired with Skyjacker Hydro 7000, Nitro 8000, BlackMAX, or M95 shocks. Hydro 7000 shocks provide velocity-sensitive hydraulic damping for smooth and predictable suspension control, while Nitro 8000 shocks use gas-charged damping for a firmer and more responsive feel. BlackMAX shocks utilize a foam-cell hydraulic design for consistent performance, while M95 monotube shocks provide improved heat dissipation and precise damping control for more demanding street and off-road applications.

With its combination of Softride front leaf springs, rear lift blocks, add-a-leafs, and supporting suspension hardware, the C180BK8 provides a comprehensive 8-inch lift solution for the 1988-1991 GMC 3/4-ton Suburban. Multiple available shock packages allow the suspension to be configured around different ride preferences and performance requirements, making this system a solid foundation for classic Suburban builds focused on increased clearance, larger tires, and improved off-road capability.
