About this kit
7.5-Inch Lift Kit with Loaded Struts, fitment-checked
Rough Country 20901 is a 7.5-inch lift kit for the 2007–2013 Chevy Avalanche in 4WD and RWD form, covering LS, LT, LTZ, and Black Diamond trims. The kit ships with a loaded strut pair, knuckles, a high-clearance crossmember, and rear components. Wheels must measure 18 inches or larger, and it will not work on Auto Ride, Auto Leveling, or electric-steering vehicles.
This 7.5-inch lift kit for the 2007–2013 Chevy Avalanche 4WD and RWD is built around a loaded strut pair, a knuckle set, and a high-clearance crossmember assembly, so the factory differential mounts, drivetrain, and exhaust stay as they are. Plan on minor cutting and drilling during the build, and confirm your wheels are 18 inches or larger before ordering. AWD vehicles need driveline work and conversion to non-AWD. Auto Ride, Auto Leveling, and electric-steering vehicles are outside the fitment. A downloadable Rough Country installation guide is available and covers approved tire and wheel combinations.
