About this kit
6-Inch Steel-Knuckle Lift Kit with M1 Shocks, fitment-checked
Rough Country 22641 is the steel-knuckle version of the 6-inch lift kit for 2014-2018 Chevy Silverado 1500 and GMC Sierra 1500 4WD trucks, plus the 2019 Silverado 1500 LD. The kit pairs an M1 loaded strut set with an M1 monotube shock pair and a high-clearance crossmember. Cutting and drilling are required, and larger tires call for the Rough Country Speedometer Calibrator, SKU 90009.
Choose this 6-inch lift kit for the 2014-2018 Chevy Silverado 1500 and GMC Sierra 1500 4WD (2019 Silverado 1500 LD applications included) when the supplied steel control arm knuckle matches your truck; confirm first whether your stock arms are cast aluminum, cast steel, or stamped steel. The parts list covers that knuckle, a crossmember box, an M1 loaded strut pair set for 6in of lift, and an M1 monotube shock pair. Cutting and drilling are part of the job, and a front differential mass damper has to come out. Denali, Denali Ultimate, and eAssist trucks fall outside fitment. Shipping weight: 217.0 lb.
