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.
Built to last
Crafted for the toughest conditions, the M1's 2-inch seamless extruded tube offers superior strength, while the 46mm digressive piston provides long-lasting durability and precise control. Digressive valving reacts instantly to changing surfaces, adapting seamlessly to rough trails and smooth streets alike.
Engineered for strength
The 18mm centerless-ground, case-hardened, chromed, and super-polished piston rod enhances durability, while a zinc-plated finish provides exceptional resistance against rust and harsh elements. No matter the conditions, the M1 is built to withstand the test of time.
Bold looks, smooth ride
Designed for both performance and aesthetics, the M1 is meant to be mounted body-up for a bold, eye-catching look. Plus, with durable vulcanized natural rubber bushings, you get a smooth, quiet ride with reduced vibrations.
Guaranteed confidence
Backed by Rough Country's 3-year manufacturer's warranty, the M1 monotube shock absorber isn't just an upgrade - it's the ultimate performance shock built to handle whatever the road throws your way.
