Bigger tires and more ground clearance start with the suspension, and a stock Chevy C30/K30 Truck/C3500/K3500 Truck runs out of room fast. With the Rough Country 6 Inch Lift Kit, the Chevy C30/K30 Truck/C3500/K3500 Truck gets its lift from parts engineered for that platform, so the geometry and ride stay where they belong. Plan the install, follow the instructions, get an alignment, then fit the tires the rig was built for.
The Rough Country 6 Inch Lift Kit (Rear Blocks) fits the Chevy C30/K30 Truck 1977-1987/C3500/K3500 Truck 1988-1991. Increased ground clearance. Installation takes about 6-8 hours. It is covered by Rough Country's Limited Lifetime Warranty.
