About this kit
3.5 Inch Lift Kit with M1 Shocks, fitment-checked
The same 3.5 inch height for the 2025 Jeep Wrangler 4WD, this time with M1 monotube shocks instead of N3. A monotube separates oil and gas, which keeps damping consistent as the shock heats up on a long rough section. OEM-based coil springs carry over. An aftermarket driveshaft is highly recommended at this height.
Shock choice is what separates the kits at this height, and the M1 is the step up. Its monotube construction keeps the gas separated from the oil, so damping does not fade the way a twin-tube can when the shock is working hard for a long stretch. The springs are the same OEM-based coils tuned to factory rates, so the ride is unchanged in character, just better controlled. The driveshaft caution applies here too, for any JL kit 3.5" or taller.
