About this kit

3.5-Inch Lift Kit with Vertex 2.5 Shocks, fitment-checked

The full Vertex 2.5 build for the 2025-2026 GMC Sierra 1500. Rough Country 110550 ships side-specific adjustable front units and a rear pair rated for 2 to 3.5 inches of lift, plus forged aluminum upper control arms. Front lift is 3.5 inches, rear 2.5 inches.

Vertex 2.5 damping at all four corners is what this kit buys you. The adjustable front units are ordered left- and right-hand specific, and the rear pair is rated across 2 to 3.5 inches of lift. Forged aluminum upper control arms with POM ball joints already installed set the geometry, producing 3.5 inches of front lift and 2.5 inches at the rear on 2025-2026 GMC Sierra 1500 4WD and RWD trucks in Elevation, Pro, SLE, and SLT trim. Denali, Denali Ultimate, AT4, AT4X, and diesel trucks are excluded. Cutting and drilling are required, and a downloadable installation guide is available.
