About this kit

3.5-Inch Lift Kit with Vertex Struts, fitment-checked

Rough Country 28857 is a 3.5-inch lift kit for compatible 2019–2024 GMC Sierra 1500 models in 4WD and RWD. The kit pairs left and right Vertex 2.5 adjustable front struts with a V2 monotube rear 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 raises the front 3.5 inches and the rear 2.5 inches, so the truck sits level rather than nose-down. Coverage spans Base, Pro, Elevation, SLE, and SLT trims, plus the 2022 Sierra 1500 Limited, in both 4WD and RWD. Contents include forged upper control arms, a strut kit box, matched Vertex 2.5 adjustable front struts, and a V2 monotube shock pair. Check the exclusion list — Classic, Denali, Denali Ultimate, AT4, AT4X, and diesel trucks are out — then work from the downloadable Rough Country installation guide.
