Rough Country's Nitrogen-charged M1 Monotube Shock Absorber upgrade your ride quality and your performance no matter how many miles you go. The Monotube M1 Shocks feature an internal floating piston design that keeps the shock oil and high-pressure nitrogen separate. The result is a super-fast reaction with no cavitation - just unbridled vibration damping at each and every obstacle. The M1 Monotube Shock Absorber is more than an average upgrade – the M1 is a true performance shock. Each shock features a steel body that is brushed and galvanized, with a passivation sealing technology that will hold up to the elements. The internal 46mm digressive piston offers long lasting durability. The M1 is designed to be mounted body-up, making the shock stand out on your rig.
