8" 1973-1986 GMC Suburban 3/4 ton 4WD Lift Kit by Skyjacker

The Skyjacker C180BK 8-Inch Suspension Lift Kit for 1973-1986 GMC 3/4-Ton Suburban 4WD models provides a substantial increase in ride height for improved ground clearance, larger tire clearance, and an aggressive lifted stance. Designed around Skyjacker Softride front leaf springs, the system combines an 8-inch front suspension lift with rear lift blocks and Softride add-a-leafs to create a balanced front-to-rear stance. The increased clearance accommodates up to 39x12.50 tires, making the C180BK a strong foundation for classic GMC builds with larger tires and improved off-road capability.

Skyjacker 8-inch Softride front leaf springs replace the factory front springs to increase ride height while maintaining useful suspension movement and articulation. At the rear, 5.5-inch tapered lift blocks work together with Softride add-a-leafs to raise the rear suspension and complement the taller front springs. Front and rear U-bolts, leaf spring bushings, brake line extensions, and supporting hardware round out the core suspension package for a comprehensive lift system engineered around the heavier-duty 3/4-ton platform.

The C180BK is available without shocks or can be configured with Skyjacker Hydro 7000, Nitro 8000, BlackMAX, or M95 shocks. Hydro 7000 shocks provide velocity-sensitive hydraulic damping for smooth and predictable suspension control, while Nitro 8000 shocks use a 150 PSI gas-charged design for a more responsive damping profile. BlackMAX shocks feature a foam-cell hydraulic design for consistent performance, while M95 shocks use 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 8 inches of suspension lift, up to 39x12.50 tire clearance, Softride front springs, rear add-a-leafs, and heavy-duty rear lift components, the C180BK provides a complete suspension upgrade for the 1973-1986 GMC 3/4-ton Suburban. Multiple shock configurations let you tailor the system to your ride and damping preferences, while the spring-and-block lift delivers the clearance classic GMC SUVs need for aggressive street styling, trail use, and off-road driving.
