About this kit

7.5-Inch Lift Kit with M1 Shocks, fitment-checked

Rough Country 26440 is a 7.5-inch lift kit for listed 2007–2013 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks, built around an M1 loaded strut pair and an M1 monotube shock pair. Wheels must be 18 inches or larger to clear the supplied knuckles, and the 2007 "Classic" body style is not covered. Minor cutting and drilling is part of the job.

This 7.5 inch lift kit for the 2007–2013 Chevrolet Silverado 1500 and GMC Sierra 1500 covers the 4WD and AWD applications listed in the fitment section, including 2008–2013 Sierra Denali, SLE, and SLT. Contents arrive as five packages: knuckles, a high-clearance crossmember, the 7.5 inch universal kit box, an M1 loaded strut pair, and an M1 monotube shock pair. Expect minor cutting and drilling during the install. AWD trucks also need aftermarket driveshaft 5083.1 to address vibration after the lift, and the 2007 "Classic" body style is excluded. Shipping weight is 222.15 lb.
