About this kit
3.5-Inch Lift Kit with N3 Shocks, fitment-checked
Rough Country 28830_A is a 3.5-inch lift kit for compatible 2025-2026 GMC Sierra 1500 models in 4WD and RWD. The box holds forged aluminum upper control arms with POM ball joints already pressed in, plus an N3 shock pair. Front ride height goes up 3.5 inches and the rear 2.5 inches. Cutting and drilling are part of the job.
This 3.5 inch lift kit for the 2025-2026 GMC Sierra 1500 fits Elevation, Pro, SLE, and SLT trims in both 4WD and RWD. It raises the front 3.5 inches and the rear 2.5 inches to even out the factory rake while opening up clearance for off-road use. Denali and Denali Ultimate trucks with Adaptive Ride Control are excluded, as are AT4 and AT4X models with their 2-inch factory lift, and the strut components do not suit diesel trucks. Plan on cutting and drilling, and read through the downloadable Rough Country installation guide before you start.
