About this kit
7.5-Inch Lift Kit, fitment-checked
Rough Country 20900 is a 7.5-inch lift kit for the 2007-2013 Chevy Avalanche in 4WD and RWD, covering LS, LT, LTZ, and Black Diamond trims. Wheels must measure 18 inches or larger. It does not fit Auto Ride or Auto Leveling suspensions or trucks with electric steering, and AWD trucks must be converted to non-AWD before the driveline will work with it.
This 7.5-inch lift kit for the 2007-2013 Chevy Avalanche 4WD and RWD ships as a five-box kit: the main hardware box, knuckles, a high-clearance crossmember, a strut spacer box, and rear lift components. The crossmember carries the differential mounts, driveline, and exhaust in their factory locations, and the struts stay assembled during the build. Plan on minor cutting and drilling, and on running 18-inch or larger wheels. Check the exclusion list against your truck first, then work from the downloadable Rough Country installation guide for the tire and wheel combinations it lists.
