About this kit
5-Inch Lift Kit, fitment-checked
Rough Country 17901 lifts the 2014–2018 GMC Sierra 1500 Denali 4WD five inches while leaving Magnetic Ride Control in place. It suits trucks with factory aluminum or stamped steel control arms, and 33-inch tires can be run on the factory 20-inch wheels.
Fitment is tight and worth checking twice: 4WD GMC Sierra 1500 Denali from 2014–2018 and Sierra Denali from 2017–2018, only with Magnetic Ride Control and only with factory aluminum or stamped steel control arms. The kit brings its own aluminum control arm knuckle, a high-clearance crossmember, and fabricated rear blocks. Installation calls for cutting and drilling, and the front differential mass damper comes off if the truck has one. Wheels need to be 18 inches or larger, and tires wider than 33x12.50 mean offset wheels and possible trimming. Shipping weight: 161 lb.
