About this kit
4-Inch Lift Kit with M1 Shocks, fitment-checked
Rough Country 33340 is a 4-inch lift kit for listed 2012–2018 Ram 1500 4WD trims and 2019–2024 Ram 1500 Classic 4WD trims. It comes with an M1 loaded strut pair and an M1 monotube shock pair. Trucks with the 3.6L Pentastar V6 or 4-Corner Air-Suspension are excluded, and 20-inch or larger wheels are required.
This 4-inch lift kit for the 2012–2018 Ram 1500 4WD also covers the 2019–2024 Ram 1500 Classic 4WD submodels shown in the fitment section. Contents include an M1 loaded strut pair, an M1 monotube shock pair, a front crossmember box kit, driver- and passenger-side knuckles, and rear coil spacers. Check the qualifiers first: it will not work with the 3.6L Pentastar V6, with 4-Corner Air-Suspension (standard on Rebel and Limited), or on Warlock trucks that already carry a 1-inch factory lift, and it is not advised for AWD because of pinion angle. Wheels must measure 20 inches or more.
