About this kit
5-Inch Lift Kit, fitment-checked
Rough Country 20800 is a 5-inch lift kit for 2007–2013 Chevy Avalanche models in 4WD and RWD, covering LS, LT, and Black Diamond LS/LT/LTZ trims. Wheels must measure 18 inches or larger, and minor cutting and drilling is part of the job. It does not fit Auto Ride or Auto Leveling trucks, and it does not fit trucks with electric steering.
This 5-inch lift kit for the 2007–2013 Chevy Avalanche 4WD and RWD ships as four boxed sub-assemblies: the main 5-inch kit box, a knuckle set, a high-clearance crossmember box, and the 5-inch front component package. The crossmember design keeps the factory differential mounts, drivetrain, and exhaust in place, and the struts do not have to be taken apart during the build. AWD trucks need driveline changes and a conversion to non-AWD. Confirm the 18-inch minimum wheel size and read through the tire and wheel guidance in the downloadable Rough Country installation guide before you order.
