Unmatched Performance: Conquer any terrain with confidence - Rough Country's Nitrogen-Charged M1 Monotube Shock Absorber delivers superior ride quality and performance mile after mile. Engineered for excellence, the M1 features an internal floating piston that keeps shock oil and high-pressure nitrogen separate, ensuring lightning-fast response with zero cavitation for unshakable vibration damping over every obstacle.

Digressive valving reacts instantly to changing surfaces, adapting seamlessly to rough trails and smooth streets alike.
