Rough Country M1 Monotube Rear Shocks | Jeep Gladiator JT 4WD (2020-2026) | 1.5-3.5" |

The Rough Country M1 Monotube Rear Shocks are designed for 2020–2026 Jeep Gladiator JT 4WD models equipped with a 1.5–3.5-inch lift. These shocks are engineered to provide improved damping, stability, and ride control for lifted Gladiators, making them an excellent upgrade for drivers who want better suspension performance both on the street and during off-road driving. The M1 shocks are sold as a pair and are specifically matched to the suspension requirements of lifted Gladiator applications.

The M1 features a 2-inch seamless extruded monotube body paired with a 46mm digressive piston. Unlike a conventional twin-tube shock, the monotube design helps maintain consistent damping performance and heat management during demanding driving conditions. The internal floating piston design separates the high-pressure nitrogen from the shock oil, allowing the shock to respond quickly to changes in terrain while helping provide consistent, fade-resistant performance.

Another important feature is the M1's self-adjusting deflective-disc valving, which independently manages rebound and compression. The digressive valving is designed to react quickly to changes in the road or trail surface, helping the Gladiator maintain better control when encountering bumps, uneven terrain, and sudden suspension movements. This makes the M1 a versatile option for both everyday driving and more aggressive off-road use.

Durability is also a major focus of the M1 design. The shocks use an 18mm centerless-ground, case-hardened, chromed, and super-polished piston rod, providing resistance to wear and corrosion. The steel shock body features a brushed and galvanized finish with zinc plating, helping protect the components from harsh environmental conditions. Durable vulcanized natural rubber bushings are also used to help absorb vibration while maintaining reliable suspension movement.

With a 16.93-inch collapsed length, 27.24-inch extended length, and approximately 10.31 inches of shock travel, these rear shocks are designed specifically around Gladiators running a 1.5–3.5-inch lift. Their eye-to-eye mounting configuration provides a direct-fit solution for compatible applications, making them a practical upgrade when replacing factory shocks on a lifted Jeep.

Overall, the Rough Country M1 Monotube Rear Shocks provide a strong combination of durability, responsive damping, and consistent performance for lifted Jeep Gladiators. Their monotube construction, 46mm digressive piston, nitrogen charging, corrosion-resistant finish, and heavy-duty piston rod make them well suited for drivers who want improved suspension control without moving to a more complex reservoir-style shock. Rough Country backs the M1 shocks with a 3-year manufacturer's warranty, providing additional confidence for long-term use.
