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.
6-Inch Lift Kit with M1 Monotube Shocks, fitment-checked
The M1 version of the 6-inch Ram 1500 lift kit: an M1 loaded strut pair up front, an M1 monotube shock pair out back, and 6-inch dual-rate rear springs. It is cut for 2025 Ram 1500 4WD trucks wearing factory 22-inch wheels, and the supplied knuckles match that hub. Air-suspension and Warlock trucks are excluded.
Running M1 monotube damping front and rear, this 6-inch kit lifts 2025 Ram 1500 4WD trucks that came from the factory on 22-inch wheels; the driver and passenger knuckles included are sized for that hub, so trucks on other factory wheels need a different part. Alongside the M1 loaded strut pair and M1 monotube rear shocks are 6-inch dual-rate rear springs and a crossmember box kit. Skip it if the truck has 4-Corner Air-Suspension, standard on Limited and Limited Longhorn, or is a Warlock with its 1-inch factory lift; AWD is not recommended. Wheels must be 20 inches or larger.
