4" 1988-1991 Chevy Suburban 3/4 ton 4WD Lift Kit (w/56" rear leaf springs) by Skyjacker

Skyjacker C140BKSD8 4 Inch Suspension Lift System for 1988-1991 Chevrolet 3/4-Ton Suburban is designed to increase ground clearance, improve off-road capability, and deliver a more aggressive stance while maintaining dependable ride quality. This complete suspension system utilizes replacement front and rear leaf springs to provide a true suspension lift, helping maintain proper suspension travel, load-carrying capability, and long-term durability.

The kit includes replacement front and rear leaf springs, front and rear U-bolt kits, and a leaf spring bushing kit for a comprehensive suspension upgrade. By replacing factory spring packs rather than relying solely on lift blocks, the C140BKSD8 restores suspension performance while providing a balanced 4-inch lift. The additional ride height allows clearance for up to 35x12.50 tires, improving both trail capability and overall vehicle appearance.

Multiple shock options are available to suit a variety of driving styles and applications. Choose from no shocks for custom builds, Black MAX shocks for dependable daily driving, Hydro 7000 hydraulic shocks for a smooth ride, Nitro 8000 nitrogen-charged shocks for enhanced control, or M95 monotube shocks for improved damping consistency and off-road performance.
