Rough Country F-150/Raptor 2WD/4WD M1 Monotube Rear Shocks (2009-2026)

Rough Country's M1 Monotube Rear Shocks bring nitrogen-charged, fade-free damping to the 2009-2026 F-150 and 2010-2025 Raptor in both 2WD and 4WD configurations. Built around a 46mm monotube design with an internal floating piston, these shocks physically separate the oil and high-pressure nitrogen charges, eliminating cavitation and delivering a consistent, rapid response whether you're crawling rocky terrain or cruising the highway. Two lift range options are available: 0-3.5 inches and 4-7.5 inches, so you can match the shock to your current suspension setup.

Fade-free performance across all conditions. The 46mm monotube construction dissipates heat more efficiently than a twin-tube design, meaning the shock maintains its calibrated damping curve even after extended hard use on rough roads or off-road trails. Digressive valving reads changing surface conditions and reacts instantly, firming up over sharp impacts and softening over long undulations without manual adjustment.

Self-adjusting compression and rebound. Deflective-disc independent rebound and compression valving adapts automatically to the input, so the shock does not require driver intervention to balance compliance on dirt with control on pavement. The 18mm centerless-ground, case-hardened, chromed, and super-polished rod resists bending and scoring under lateral load, extending seal life and keeping the action smooth over the long term.

Built to survive the elements. The steel body features a brushed and galvanized finish with passivation sealing technology that guards against rust and corrosion. Zinc plating adds another layer of protection for trucks that see mud, road salt, or regular water crossings. Durable vulcanized natural rubber bushings complete the package, absorbing noise and vibration at the mounting points without the harshness of polyurethane.
