About this kit
Vertex 2.5 Front and Rear 3.5-Inch Lift Kit, fitment-checked
Vertex damping front and rear on a 3.5-inch lift for the 2025-2026 Silverado 1500. The kit lists forged aluminum upper control arms, left and right adjustable Vertex 2.5 front units, and two Vertex 2.5 rear shocks. The front rises 3.5 inches, the rear 2.5 inches. Expect cutting and drilling. Trail Boss, ZR2, and Adaptive Ride Control models are excluded.
Among the 4WD and RWD Silverado 1500 trims listed for 2025-2026, this 3.5-inch lift kit is the one that carries Vertex 2.5 damping at all four corners — adjustable side-specific units up front, a matched pair in back. Forged aluminum upper control arms come with the POM ball joints already installed. The front rises 3.5 inches and the rear 2.5 inches. Cutting and drilling are required, and a downloadable Rough Country installation guide is available. Confirm the truck is not a Trail Boss or ZR2 and has no Adaptive Ride Control. Shipping weight is 143.5 lb.
