8" 1977-1986 GMC Pickup 1 ton 4WD Lift Kit by Skyjacker

The Skyjacker C180CK 8-Inch Suspension Lift Kit for 1977-1986 GMC 1-Ton Pickup 4WD models delivers substantial ground clearance, increased tire clearance, and an aggressive lifted stance for the heavy-duty K30 platform. This system combines Skyjacker Softride 8-inch front leaf springs with 5.5-inch tapered rear lift blocks and rear Softride add-a-leafs to increase suspension height. With clearance for up to 39x12.50 tires, the C180CK provides a comprehensive suspension upgrade for classic Chevy 1-ton trucks built for larger tires, increased clearance, and improved off-road capability.

Skyjacker Softride front leaf springs replace the factory front springs and provide the full 8-inch front lift while maintaining useful suspension movement and articulation. At the rear, 5.5-inch tapered lift blocks work with Softride add-a-leafs to raise the rear suspension and complement the taller front spring configuration. Front and rear U-bolts, a leaf spring bushing kit, brake line extensions, and supporting hardware complete the core suspension package and provide the components needed to accommodate the significantly increased ride height.

The C180CK is available without shocks or can be configured with Skyjacker Hydro 7000, Nitro 8000, BlackMAX, or M95 shocks. Hydro 7000 shocks use velocity-sensitive hydraulic damping for smooth, predictable suspension control, while Nitro 8000 shocks feature a 150 PSI gas-charged design for a firmer, more responsive damping profile. BlackMAX shocks utilize a foam-cell hydraulic design for consistent performance, while M95 shocks feature a 200 PSI gas-charged monotube design with an internal floating piston for improved heat management and controlled damping during more demanding driving conditions.

With its combination of 8-inch Softride front springs, tapered rear blocks, rear add-a-leafs, and supporting suspension components, the C180CK provides the height and strength needed for a significantly lifted 1977-1986 GMC 1-ton pickup. The system supports up to 39x12.50 tires and offers multiple shock configurations, letting you tailor the suspension to different ride preferences and performance demands while maintaining the rugged leaf-spring architecture of the classic GMC K30.
