Bigger tires and more ground clearance start with the suspension, and a stock Chevy/GMC 3/4-Ton Suburban/C20/K20 Truck runs out of room fast. With the Rough Country 4 Inch Lift Kit, the Chevy/GMC 3/4-Ton Suburban/C20/K20 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 4 Inch Lift Kit (Rear Blocks) fits the Chevy/GMC 3/4-Ton Suburban/C20/K20 Truck/C25/K25 Truck 1973-1976. Increased ground clearance.
