Due to differences in hub sizing this kit does NOT work on 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 M1 Monotube Shocks, fitment-checked
The M1 route to 6 inches on a 2025 Ram 1500 4WD: 88340 pairs an M1 loaded strut pair with an M1 Monotube shock pair, dual-rate rear coil springs, and driver and passenger knuckles made for the 2025 truck. Trucks with factory 22-inch wheels are out on hub sizing, and 20-inch or larger wheels are required. Warlock and 4-Corner Air-Suspension models are not covered.
Same 6-inch geometry as the rest of the 2025 Ram 1500 4WD range, with M1 Monotube hardware doing the damping: an M1 loaded strut pair at the front, an M1 Monotube shock pair, dual-rate rear coil springs, a crossmember box kit and knuckles specific to this truck. Trims run from Tradesman, Tradesman HFE and Express up through Tungsten, Limited and Limited Longhorn, with Rebel and RHO covered. Check the wheels before anything else — hub sizing means factory 22-inch wheels will not work, and 20 inches is the minimum diameter either way. Warlock and 4-Corner Air-Suspension trucks are excluded; AWD is not recommended. Shipping weight: 285.0 lb.
