Lifted F-250 Super Duty trucks demand shocks that can keep pace with the added suspension travel and the punishment that comes with serious off-road use. Rough Country's M1 Monotube front shocks deliver nitrogen-charged, fade-free damping calibrated specifically for 7.5 to 8 inch lifted 2005 to 2026 4WD F-250 Super Duty applications, replacing the factory units with a true performance shock absorber.
Monotube design with internal floating piston. Unlike twin-tube shocks, the M1's monotube construction uses a floating piston to keep shock oil and high-pressure nitrogen gas completely separated. That separation eliminates cavitation under hard use, so the shock reacts instantly to changing terrain without the fade or foamy oil that plagues lesser designs.
Digressive valving for real-world versatility. The 46mm digressive piston reads surface conditions continuously and adjusts rebound and compression independently through self-adjusting deflective discs. Smooth pavement, washboard dirt roads, and rocky trails all get an appropriate damping response without manual adjustment.
Built to endure the elements. The shock body starts as a 2 inch seamless extruded tube, then receives a zinc-plated, brushed, and galvanized finish with passivation sealing technology. The 18mm centerless-ground, case-hardened, chromed, and super-polished rod resists corrosion and scoring across years of hard use. Durable vulcanized natural rubber bushings absorb noise and vibration at the mounting points.
Body-up mounting orientation. The M1 is designed to mount body-up, positioning the larger shock body at the top of the stroke for a cleaner look on a lifted truck while keeping the working components in their optimal operating position.
