4" 1973-1986 GMC Pickup 3/4 ton 4WD Lift Kit by Skyjacker

Skyjacker C140BK 4 Inch Suspension Lift Kit for 1973-1986 GMC 3/4-Ton Pickup Trucks is designed to increase ground clearance, improve off-road capability, and provide a more aggressive stance while maintaining dependable ride quality and load-carrying performance. This complete suspension system includes replacement front leaf springs, front and rear U-bolt kits, a front leaf spring poly bushing kit, rear lift blocks, and your choice of shock options to match your driving style and vehicle demands.

Built around replacement front leaf springs rather than spacer-based components, the C140BK delivers a true 4-inch suspension lift while helping maintain proper suspension travel and durability. Rear lift blocks complement the front suspension upgrades to create a balanced lift height, allowing clearance for up to 35x12.50 tires while improving trail capability and overall vehicle appearance.

Available shock configurations allow the system to be customized for a wide range of 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. Whether the truck is used for work, towing, restoration, or recreation, this system provides a solid foundation for improved capability.
