M1R Monotube Rear Shocks | 2.5-4.5" | Chevy/GMC Canyon/Colorado (23-26)

Rough Country M1R Monotube Rear Shocks deliver unmatched control and enduring performance for Chevy/GMC Canyon and Colorado owners (model years 23–26). Engineered to work with 2.5–4.5-inch lift applications, these shocks are built to handle the heaviest loads and the roughest terrain—on road or off.

Key advantages include advanced heat management, precise damping, and rugged durability that keeps your ride responsive even after repeated abuse.

• 46mm monotube with external reservoir accelerates heat dissipation and maintains fade-free damping across long, demanding sessions.
• Internal floating piston separates oil and gas for consistent performance under extreme use.
• 2-inch digressive piston with self-adjusting deflective-disc valving adapts to changing terrain, delivering smooth ride and confident handling whether you’re on pavement or crawling over rocks.
• 2-inch seamless extruded body paired with a 16mm case-hardened, chromed rod for maximum strength and longevity.
• Galvanized zinc finish protects against corrosion, while natural rubber bushings minimize noise and vibration for a quieter ride.

What this means for you

• Improved ride quality and steering control when towing or carrying gear on rough backroads.
• Enhanced off-road capability with consistent damping on washboards, ruts, and steep descents.
• Longer component life thanks to robust construction and corrosion resistance.

Quality you can rely on

• Rugged, weather-ready construction that’s designed to withstand harsh environments and heavy use.
• 3-year manufacturer's warranty provides confidence that this upgrade is built to last.
