About this kit
2.5-Inch Leveling Kit with M1 Shocks, fitment-checked
Rough Country 63440 levels the 2020–2023 Jeep Gladiator 4WD by 2.5 inches and replaces the dampers at the same time — the 63400 spacer kit plus two pairs of M1 monotube shocks. No cutting or drilling. Not compatible with Mojave models equipped with 2.5 shocks.
Choosing between shock options is most of the decision on this kit, and 63440 is the M1 monotube version: two M1 pairs packed with the 63400 spacer kit to level the 2020–2023 Jeep Gladiator 4WD by 2.5 inches. Sway bar links and bump stops are in the box, and the install is bolt-on with no cutting or drilling. Fitment reaches Sport through Rubicon, including Freedom, Texas Trail, Willys, and Overland trims. Tires up to 35 inches clear, with a clearance check advised on factory wheels. Mojave models equipped with 2.5 shocks are excluded. A downloadable installation guide is available.
