M1R Monotube Rear Shocks | 3-6.5" | Chevy/GMC 2500 SUV 2WD/4WD (2000-2010)

Take control of your Chevy/GMC 2500’s rear suspension with Rough Country's M1R Monotube Rear Shocks. Designed to handle heavy loads and rough terrain, these shocks strike the perfect balance between precise handling and ride comfort, so your truck stays composed whether you’re towing, hauling, or exploring backroads.

Advanced design for heat management and consistent damping

The M1R pairs a robust 46mm monotube design with an external reservoir to shed heat quickly, delivering fade-free performance even under extended demanding use. An internal floating piston separates oil and gas, ensuring stable damping across a wide range of temperatures and pressures.

• 46mm monotube with external reservoir for rapid heat dissipation and sustained damping under heavy load.
• Internal floating piston isolates oil from gas to maintain consistent performance when the going gets tough.
• 2-inch digressive piston paired with self-adjusting deflective-disc valving automatically adapts to changing terrain for superior handling on road and trail.
• Rugged construction: 2-inch seamless extruded body, 16mm case-hardened chromed rod, and galvanized zinc finish resist corrosion; natural rubber bushings minimize noise and vibration.

Why this matters for your daily drive and adventures

Rough Country engineered the M1R to deliver confident ride quality when you’re loaded with gear, towing a trailer, or navigating rough dirt roads. The progressive damping profile keeps you connected to the surface, reducing wheel hop and preserving tire contact so you can accelerate, brake, and corner with authority—whether you’re on pavement or off the beaten path.

Durability that goes the distance

These shocks are built to endure in demanding environments. The combination of a rugged 2-inch body, robust rod, and corrosion-resistant finish means long-lasting performance year after year. The natural rubber bushings further reduce unwanted movement and noise, contributing to a quieter, more controlled ride when the vehicle is loaded or driven aggressively.
