Rough Country's M1 Monotube Rear Shocks deliver nitrogen-charged, fade-free damping for 2017-2018 F-150 Raptor builds running 4 to 6 inches of lift. The monotube design keeps shock oil and high-pressure nitrogen separated by an internal floating piston, eliminating cavitation and producing a rapid, consistent response across every type of terrain. Sold in pairs, these shocks install body-up for a clean, purposeful look under the rear of the truck.
Monotube construction without compromise. The 46mm digressive piston and 46mm monotube body resist heat fade across extended off-road runs, where twin-tube shocks commonly cavitate and lose damping force. Digressive valving reacts instantly to changing surface conditions, firming up under hard inputs and softening for smaller chatter without driver intervention.
Built to handle the elements. Each shock body is constructed from a 2-inch seamless extruded tube with zinc plating for corrosion resistance. The 18mm centerless-ground, case-hardened, chromed, and super-polished rod minimizes friction and resists pitting, while self-adjusting deflective-disc independent rebound and compression valving keeps the tune consistent over the life of the shock.
Ready to install, ready to last. Durable vulcanized natural rubber bushings absorb noise and vibration at the mounting points, and the straightforward bolt-in design allows a typical rear installation in one to two hours. Rough Country backs each M1 shock with a 3-year manufacturer's warranty.
