8" 1988-1991 GMC Jimmy 4WD Lift Kit (w/rear leaf springs) by Skyjacker

The Skyjacker C180AKS8 8-Inch Suspension Lift Kit for 1988-1991 GMC Jimmy 4WD models is a complete front and rear leaf spring suspension system that provides substantial ground clearance, increased tire clearance, and a commanding lifted stance. Unlike block-based rear lift configurations, the C180AKS8 uses Skyjacker Softride leaf springs at both ends to achieve the full 8-inch suspension lift. The system also includes front and rear U-bolt kits, leaf spring bushings, brake line brackets, and the supporting hardware needed to integrate the taller springs into the factory leaf-spring suspension.

Skyjacker Softride 8-inch front and rear leaf springs form the foundation of the C180AKS8 system. Replacing the factory springs at both axles provides a spring-based increase in ride height while maintaining useful suspension movement and articulation for street and off-road driving. The matched front and rear spring configuration creates a balanced suspension setup while providing the additional chassis clearance needed for larger tires and more demanding terrain.

The C180AKS8 is available without shocks or with a choice of Skyjacker Hydro 7000, Nitro 8000, BlackMAX, or M95 shocks. Hydro 7000 shocks provide velocity-sensitive hydraulic damping for smooth, controlled operation, while Nitro 8000 gas-charged shocks deliver a more responsive damping profile. BlackMAX shocks use a foam-cell hydraulic design to maintain consistent performance, while M95 monotube shocks provide enhanced heat dissipation and precise damping control for more demanding driving conditions.

With a full 8 inches of suspension lift and replacement Softride leaf springs at both the front and rear, the C180AKS8 provides a comprehensive suspension upgrade for the 1988-1991 GMC Jimmy. Its combination of increased ride height, durable leaf-spring construction, supporting suspension hardware, and multiple shock options makes it a strong foundation for classic Blazer builds focused on larger tires, increased ground clearance, aggressive styling, and improved off-road capability.
