Whether you're cruising city streets or charging over tough terrain, Rough Country's nitrogen-charged M1 Monotube Shock Absorber delivers uncompromising ride quality and long-lasting performance. Designed with an internal floating piston, the M1 separates shock oil from high-pressure nitrogen for lightning-fast response and zero cavitation - ensuring smooth, consistent damping with every impact. The 46mm digressive piston reacts instantly to changing surface conditions, while the self-adjusting deflective-disc valving fine-tunes rebound and compression on the fly.
Built for durability and style, each M1 shock features a brushed and galvanized steel body with passivation sealing tech to resist the harshest elements. An 18mm centerless ground, chromed, and polished rod adds strength and corrosion resistance, while natural rubber bushings absorb road vibrations for a quieter ride. The inverted body-up mount provides a bold look on any build, and with multiple lift height options available, the M1 is ready to match your rig's setup. It's more than a shock - it's a true suspension upgrade. Sold in pairs, every M1 shock absorber is backed by Rough Country's 3-year Manufacturer's Warranty for confidence you can count on.
