About this kit

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

Rough Country 78940 is a 3.5-inch lift kit for 2024–2026 Jeep Gladiator 4WD, built around dual-rate front and rear coil springs and two pairs of M1 Monotube shocks. It does not fit Mojave models running the factory 2.5 shocks, which use a larger shock bolt than these replacement shocks accept.

This 3.5-inch lift kit for the 2024–2026 Jeep Gladiator 4WD covers Sport, Sport S, Willys, Rubicon, Rubicon X, High Tide, NightHawk, Jeep Beach, and Texas Trail applications listed in the fitment section. The box ships with front and rear dual-rate coil springs plus two M1 Monotube shock pairs, and the springs are rated close to factory to keep ride quality familiar. A forged track bar with 1.25-inch diameter and OEM-style rubber bushings keeps the axle centered. Installation bolts on with no cutting or welding, and a downloadable installation guide is available. Confirm the Mojave shock exclusion before ordering.
