6" 2001-2010 Chevy Silverado 2500HD/3500 Lift Kit by Skyjacker

The Skyjacker C9681K 6-Inch Suspension Lift Kit for 2001-2010 Chevy Silverado 2500HD and 3500 models is a complete heavy-duty suspension system that delivers substantial ground clearance, increased tire clearance, and properly relocated suspension geometry at the taller ride height. The system combines replacement steering knuckles, heavy-duty front and rear crossmembers, torsion bar drop brackets, front bump stop brackets, a differential skid plate, rear lift blocks, a rear add-a-leaf, U-bolts, and supporting suspension hardware. Shock options include Skyjacker Hydro 7000, Nitro 8000, BlackMAX, or M95 Performance shocks, offering several damping configurations to match different ride and performance preferences.

The front suspension uses application-specific replacement steering knuckles to accommodate the 6-inch ride-height increase while maintaining controlled steering operation. Heavy-duty front and rear crossmembers relocate critical lower suspension mounting points and provide a rigid structural foundation for the lifted independent front suspension. Torsion bar drop brackets reposition the factory torsion bar system to work with the taller suspension, while driver- and passenger-side bump stop brackets account for the revised suspension position and compression travel. An integrated differential skid plate protects critical front drivetrain components while reinforcing the crossmember-based suspension layout.

At the rear, lift blocks and a Skyjacker add-a-leaf work with the factory leaf spring suspension to provide the additional height needed to complement the 6-inch front lift. The add-a-leaf increases spring support, while the rear block system sets the required ride height, creating a balanced front-to-rear stance without replacing the factory spring packs. The C9681K suspension system provides clearance for up to 35x12.50 tires with properly configured wheels, making it well suited for heavy-duty Silverado builds focused on increased ground clearance, larger tires, and improved street and off-road capability.

The C9681K is available with four Skyjacker shock configurations. Hydro 7000 shocks use velocity-sensitive hydraulic damping for smooth, predictable suspension response on everyday street and trail drives. Nitro 8000 shocks use a 150 PSI gas charge for firmer, more responsive damping and increased suspension control over changing terrain. BlackMAX shocks feature advanced foam-cell hydraulic technology for consistent damping without a high-pressure gas charge, while M95 Performance shocks use a 200 PSI gas-charged monotube internal floating piston design with a large 46mm bore for responsive damping, improved heat management, and consistent performance during more demanding driving conditions.
