About this kit
4.75-Inch Lift Kit with N3 Shocks, fitment-checked
Rough Country 292.20 combines a 3.5 inch suspension lift with a 1.25 inch body lift for a 4.75 inch total on 2014–2015 Chevrolet Silverado 1500 and GMC Sierra 1500 4WD trucks. It fits only trucks that left the factory with cast steel control arms — cast aluminum and stamped steel arms are not supported. Minor cutting is part of the job.
This 4.75 inch lift kit for the 2014–2015 Silverado 1500 and Sierra 1500 4WD stacks two Rough Country kits: a 3.5 inch aluminum/cast steel suspension lift with N3 series shocks, differential drops to hold axle angle, and pre-installed ball joints, plus a 1.25 inch body lift using fiberglass-reinforced nylon pucks. Fabricated rear lift blocks replace the factory block. The body lift portion covers standard cab and 4-door trucks, includes front bumper brackets, and relocates the rear bumper on factory brackets. Confirm your control arm material first, then use the downloadable installation guide to plan the work.
