About this kit
7.5-Inch Lift Kit with M1 Shocks, fitment-checked
Rough Country 25340 is a 7.5-inch lift kit built around two M1 monotube shock pairs for the 2011-2019 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD in the 4WD and RWD trims listed in fitment. Dually trucks and trucks with Magnetic Ride Control are not covered, and factory wheels will not clear the kit.
Front and rear M1 monotube shock pairs ship with this 7.5-inch lift kit for the 2011-2019 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD, together with a crossmember box, the main and rear kit boxes, a bracket box, and driver- and passenger-side knuckles. Torsion bars stay in their factory location and track width is unchanged. Plan on minor cutting and drilling. Trucks with factory 17-inch wheels need aftermarket wheels of 17 inches or larger for caliper and rotor clearance, and trucks with factory rear overload springs need the longer u-bolt kit 7664. A downloadable installation guide is available.
