About this kit
3.5-Inch Lift Kit with Red Control Arms, fitment-checked
Rough Country 18901RED is a 3.5-inch lift kit built specifically for the 2014-2016 GMC Sierra 1500 Denali 4WD with Magnetic Ride Control. Red forged upper control arms rated for 2.5-3.5 inches of lift ship with the ball joints already pressed in, and a fabricated rear block replaces the factory unit. Cutting and grinding are required.
Denali with Magnetic Ride Control is the whole target here — this 3.5-inch kit is built for that combination on the 2014-2016 GMC Sierra 1500 4WD and nothing else. The red forged upper control arms are rated for 2.5-3.5 inches of lift and arrive with ball joints pressed in, differential drops keep axle angles where they belong, and a fabricated rear block takes the place of the factory one. Trucks running stamped steel upper control arms from 2016 on are excluded, and cutting and grinding are part of the job. Factory wheels can be kept with a 0.25-inch wheel spacer, part 1065.
