About this kit
3.5-Inch Lift Kit with M1 Struts, fitment-checked
Rough Country 28840 is a 3.5-inch lift kit for 2019-2024 GMC Sierra 1500 in 4WD and RWD, pairing 3.5 inches of front lift with 2.5 inches at the rear to even out factory rake. The box holds an M1 loaded strut pair, an M1 monotube shock pair, and forged aluminum upper control arms with pre-installed POM ball joints. It does not fit 2019 Classic (2018 body style), Denali, Denali Ultimate, AT4, AT4X, or diesel trucks.
This 3.5-inch lift kit for the 2019-2024 GMC Sierra 1500 covers Base, Elevation, Pro, SLE, and SLT trims in both 4WD and RWD, plus the 2022 Sierra 1500 Limited applications listed in the fitment section. Front lift measures 3.5 inches against 2.5 inches in the rear, so the truck sits level rather than nose-down. Forged aluminum upper control arms arrive with ball joints already pressed in to shorten bench time. Confirm your trim against the exclusion list first, then work from the downloadable Rough Country installation guide.
