Rough Country M1 Monotube Rear Shocks | Jeep Gladiator JT 4WD (2020-2026) | 0-2.5" |

The Rough Country M1 Monotube Rear Shocks are designed for 2020–2026 Jeep Gladiator JT 4WD models with 1.5–3.5 inches of lift, providing an upgraded suspension solution for drivers looking for improved control, stability, and durability. The M1 series is built specifically for lifted applications and is engineered to maintain consistent damping performance whether the Gladiator is being driven on pavement, carrying additional weight, or navigating rough off-road terrain. Rough Country currently lists the rear M1 shocks for the 1.5–3.5-inch lift range, while its 0–2.5-inch M1 application is listed for the front suspension.

At the center of the M1 design is a 2-inch seamless extruded monotube body and a 46mm digressive piston. The monotube construction allows the shock to better manage heat during demanding driving conditions while maintaining consistent damping performance. Its digressive valving is designed to react quickly to changing road and trail surfaces, helping the Gladiator maintain better control when traveling over bumps, uneven terrain, and other obstacles.

The M1 also features a self-adjusting deflective-disc design that independently manages compression and rebound forces. This allows the shock to respond appropriately to different suspension movements, providing a balance between ride comfort and controlled handling. The design is particularly useful for lifted Gladiators because proper shock damping becomes increasingly important as suspension travel and tire size increase.

Durability is another important part of the M1 construction. The shocks use an 18mm centerless-ground, case-hardened, chromed, and super-polished piston rod, designed to withstand repeated suspension movement while resisting wear and corrosion. The shock body is zinc plated for additional protection against harsh environmental conditions, while durable vulcanized natural rubber bushings help absorb vibration and provide reliable mounting performance.

Designed for Gladiators running a 1.5–3.5-inch lift, these rear shocks provide approximately 10.31 inches of shock travel, with a 16.93-inch collapsed length and 27.24-inch extended length. Their application-specific design makes them a practical direct-fit upgrade for compatible lifted Gladiator suspension setups.

Overall, the Rough Country M1 Monotube Rear Shocks offer a strong combination of responsive damping, heat management, durability, and off-road capability. With their monotube construction, large 46mm piston, digressive valving, heavy-duty piston rod, and corrosion-resistant finish, they are an excellent choice for Jeep Gladiator owners running a 1.5–3.5-inch lift who want more controlled and dependable suspension performance. Rough Country backs the M1 shocks with a 3-year manufacturer's warranty.
