Detail About this part

What it is

Unmatched Control. Maximum Performance: Rough Country's M1R Monotube Shocks with External Reservoir deliver the perfect blend of control, comfort, and endurance. Designed to handle the harshest terrains and heaviest loads, the M1R ensures your ride performs at its peak, on or off the road.

Built for Heat, Engineered for Pressure: Featuring an advanced 46mm monotube design and external reservoir, the M1R delivers faster heat dissipation and fade-free performance in any environment. An internal floating piston separates oil and gas for consistent damping, even during extreme use.

Precision Performance and Comfort: With a 2-inch digressive piston and self-adjusting deflective-disc valving, the M1R adapts to changing terrains on the fly, giving you superior handling and ride quality. Whether cruising pavement or crawling trails, experience control without compromise.

Unyielding Strength, Built to Last: From the 2-inch seamless extruded body to the 16mm case-hardened, chromed rod, every component is crafted for extreme durability. The galvanized zinc finish protects against corrosion, while natural rubber bushings minimize noise and vibration.

Confidence You Can Count On: Backed by Rough Country's 3-year manufacturer's warranty, the M1R is built to go the distance, reliable, rugged, and ready for anything.
