8" 1988-1991 GMC Suburban 3/4 ton 4WD Lift Kit (w/rear leaf springs) by Skyjacker

The Skyjacker C180BKSD8 8-Inch Suspension Lift Kit for 1988-1991 GMC 3/4-Ton Suburban 4WD models is a complete suspension system designed for applications equipped with 56-inch rear springs. This system provides a full 8 inches of lift using Skyjacker Softride front and rear leaf springs, increasing ground clearance and creating additional room for larger tire combinations. The C180BKSD8 combines replacement leaf springs with rear lift blocks and supporting suspension hardware to create a comprehensive front-to-rear upgrade for the heavy-duty 8-lug Suburban platform.

Skyjacker Softride leaf springs replace the factory front and rear spring packs to increase suspension height while maintaining usable suspension movement and articulation. The system pairs 8-inch front Softride springs with replacement rear Softride springs and 2-inch rear lift blocks to achieve the intended stance. Front and rear U-bolt kits, leaf spring bushings, brake line brackets, and related hardware support the taller suspension configuration and provide the components needed to properly integrate the lift with the factory leaf-spring layout.

The C180BKSD8 is available without shocks or can be configured with Skyjacker Hydro 7000, Nitro 8000, BlackMAX, or M95 shocks. Hydro 7000 shocks provide velocity-sensitive hydraulic damping for smooth, predictable suspension control, while Nitro 8000 gas-charged shocks deliver a firmer, more responsive damping profile. BlackMAX shocks utilize a foam-cell hydraulic design for consistent performance, while M95 monotube shocks provide enhanced heat dissipation and controlled damping for more demanding street and off-road use.

With 8 inches of suspension lift, replacement front and rear Softride leaf springs, 2-inch rear blocks, and multiple available shock configurations, the C180BKSD8 provides a substantial suspension upgrade for the 1988-1991 GMC 3/4-ton Suburban. The complete spring-based system delivers the increased chassis clearance and lifted stance expected from an 8-inch suspension system while retaining a durable configuration suited to the size and weight of the classic 3/4-ton Suburban.
