4" 1973-1986 Chevy Suburban 3/4 ton 4WD Lift Kit (w/rear 56" leaf springs) by Skyjacker

Skyjacker C140BKSD 4 Inch Suspension Lift System for 1973-1986 Chevrolet 3/4-Ton Suburban models is designed to increase ground clearance, improve off-road capability, and deliver a more aggressive stance while maintaining dependable ride quality. Specifically engineered for vehicles equipped with 56-inch rear leaf springs, this complete suspension system utilizes replacement front and rear leaf springs to provide a true suspension lift while preserving proper suspension travel and load-carrying performance.

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 C140BKSD restores suspension performance while providing a balanced 4-inch lift. The additional ride height creates clearance for up to 35x12.50 tires, improving trail capability and giving your Suburban a more commanding appearance.

Multiple shock configurations are available to suit a wide 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.
