Description

The Rough Country M1 Monotube Rear Shock Absorber is engineered for superior ride quality and performance, whether on tough terrain or city streets. Its advanced monotube design utilizes an internal floating piston to keep oil and nitrogen separate, ensuring a lightning-fast reaction without cavitation for optimal vibration damping. The shock absorber features a robust 2-inch seamless extruded tube and a 46mm digressive piston for years of durability. Its self-adjusting, deflective-disc system provides independent rebound and compression control, while the 18mm centerless-ground, case-hardened, chromed, and super-polished rod enhances longevity. Constructed with a zinc-plated steel body, this shock absorber is brushed, galvanized, and treated with passivation sealing technology to resist harsh elements. The digressive valving instantly adapts to changing surface conditions, providing consistent, fade-free performance. The M1 Monotube Shock Absorber is backed by a 3-year manufacturer's warranty and includes free shipping. Installation is estimated to take 1-2 hours.
