Due to differences in hub sizing this kit ONLY fits models equipped with factory 22" wheels. This package is an available upgrade across multiple sub-models. Kit is NOT recommended for AWD models due to pinion angle issues which cause drivetrain vibrations. Fitment on this page is based on the manufacturer’s application data.
About this kit
6-Inch Lift Kit with Vertex 2.5 Shocks, fitment-checked
Vertex 2.5 damping at every corner: adjustable Vertex 2.5 front struts, left and right, plus a pair of Vertex 2.5 rear shocks and 6-inch dual-rate rear springs. Built for 2025 Ram 1500 4WD trucks with factory 22-inch wheels. Wheels must measure 20 inches or larger, and air-suspension, Warlock, and AWD trucks are excluded.
This is the full Vertex build of the 6-inch Ram 1500 lift kit: adjustable Vertex 2.5 front struts in left and right form, two Vertex 2.5 rear shocks, 6-inch dual-rate rear springs, a crossmember box kit, and hub-specific driver and passenger knuckles. Those knuckles limit it to 2025 Ram 1500 4WD trucks that came on factory 22-inch wheels. Before ordering, rule out 4-Corner Air-Suspension, standard on Limited and Limited Longhorn, and Warlock, which already has a 1-inch factory lift; AWD is not recommended. Wheels of 20 inches or larger are required.
