About this kit
6-Inch Lift Kit with Vertex 2.5 Shocks, fitment-checked
Vertex 2.5 damping at all four corners: side-specific adjustable front units and a pair of 7 in rear shocks, wrapped around a 6-inch lift for the 2025–2026 GMC Sierra 1500 in Elevation, Pro, SLE, and SLT. Denali, Denali Ultimate, AT4, and AT4X trucks are excluded, and the install calls for cutting and drilling.
The draw here is adjustable damping. Left and right Vertex 2.5 front shocks are matched to the 6-inch height, and two 7 in Vertex 2.5 shocks go in at the rear, giving a range to dial in instead of a single fixed valving. Structure is shared with the rest of the Sierra 1500 6-inch family: high-clearance crossmember, full front skid plate, cast driver and passenger knuckles, and fabricated rear blocks. Elevation, Pro, SLE, and SLT trucks from 2025–2026 fit in 4WD or RWD; Denali, Denali Ultimate, AT4, and AT4X do not. Cutting and drilling are required.
