About this kit
3.5-Inch Lift Kit, fitment-checked
Rough Country 27731RED is a 3.5-inch lift kit for compatible 2007-2013 Chevrolet Silverado 1500 4WD and GMC Sierra 1500 4WD/AWD trucks. The box holds a loaded strut pair and red forged upper control arms rated for 2.5-3.5 inches of lift, with pre-installed POM ball joints. Cutting and grinding are part of the job, and the factory rear block is swapped for a fabricated steel one.
This 3.5-inch lift kit for the 2007-2013 Silverado 1500 4WD and Sierra 1500 4WD/AWD (GMC Sierra listings also run 2010-2013) fits trucks with cast steel or cast aluminum factory upper control arms only. Verify which arms your truck has first: stamped steel arms need the 3.5 inch knuckle kit instead because of CV boot clearance. It will not work on 2014-2016 Denali models with Magnetic Ride Control or on eAssist hybrid trucks. A front-differential mass damper, where fitted, has to come off to drop the differential. Cutting and grinding required; a downloadable installation guide is available.
