About this kit

3.5-Inch Lift Kit with M1 Shocks, fitment-checked

Rough Country 63740 is a 3.5-inch lift kit for the 2020–2023 Jeep Gladiator 4WD, built around two M1 monotube shock pairs and a forged front track bar rated for 2.5-6 inch lift heights. It does not fit Mojave models running FOX 2.5 shocks, which use a larger shock bolt.

This 3.5-inch lift kit for the 2020–2023 Jeep Gladiator 4WD covers Sport, Sport S, Willys, Willys Sport, Overland, Rubicon, Altitude, High Altitude, 80th Anniversary, Launch Edition, and Texas Trail applications listed in the fitment section. Rough Country lists the kit as a bolt-on installation that levels the front with the rear and opens up room for tires as large as 37 inches. The forged front track bar uses a 1.25-inch outside diameter tube with OEM-style rubber bushings to keep the axle centered. Confirm your Gladiator is not a Mojave with FOX 2.5 shocks, then work from the downloadable Rough Country installation guide.
