Rough Country 28830RED_A is a 3.5-inch lift kit for compatible 2025–2026 GMC Sierra 1500 models in 4WD and RWD. The kit pairs red forged aluminum upper control arms with an N3 shock pair and raises the rear 2.5 inches for a level stance. Installation requires cutting and drilling, and the kit does not fit Denali, Denali Ultimate, AT4, AT4X, or diesel models.

Front lift measures 3.5 inches with 2.5 inches at the rear. The forged aluminum upper control arms use POM ball joints that arrive already pressed in, and an N3 shock pair ships in the same kit box.
