About this kit

Vertex 2.5 6-Inch Lift Kit, fitment-checked

21750 is the Vertex 2.5 build of the 6-inch Silverado 1500 lift kit, covering 2019–2024 4WD trucks and the 2022 Silverado 1500 LTD. Front damping comes from side-specific Vertex 2.5 adjustable units; the rear runs two 7-inch Vertex 2.5 shocks. Cast knuckles, a high-clearance crossmember, and a front full skid plate complete the kit.

Anyone specifying a 6-inch lift kit for a 2019–2024 Chevy Silverado 1500 4WD who wants adjustable damping lands here. Left- and right-specific Vertex 2.5 front shocks pair with a set of 7-inch Vertex 2.5 rears, mounted to the same cast knuckle and high-clearance crossmember hardware used across the platform. Wheels are the gating item: factory wheels are out, and aftermarket replacements need 20 inches of diameter and 4.5in backspacing, with a 0.25 inch spacer occasionally required. Cutting and drilling apply; a downloadable installation guide is available. Shipping weight: 318.37 lb.
