Lifted Super Duty trucks demand shocks that can keep pace with added suspension travel, heavier loads, and punishing terrain. Rough Country's M1 Monotube Rear Shocks give 2017-2026 F-250 and F-350 Super Duty owners running 5-7.5 inches of lift a purpose-built damping solution that handles off-road abuse and highway miles with equal composure. Sold in pairs, these shocks install in 1-2 hours without cutting or fabricating.
Monotube construction eliminates fade. The internal floating piston keeps high-pressure nitrogen and shock oil completely separated, preventing cavitation and aeration under hard use. The 46mm monotube design delivers consistent, fade-free damping whether you are crawling over rock ledges or running loaded on the interstate.
Digressive valving reacts instantly to changing conditions. The self-adjusting, deflective-disc independent rebound and compression valving reads the terrain and responds without delay. Soft hits get a compliant response; sharp impacts get firm, controlled damping. The result is a ride that stays planted and predictable rather than bouncy or harsh.
Built to survive years of exposure. Each shock body starts as a 2-inch seamless extruded tube, finished with zinc plating and passivation sealing technology to resist rust and corrosion. The 18mm centerless-ground, case-hardened, chromed, and super-polished rod resists scoring and seal wear. Durable vulcanized natural rubber bushings complete the package for long-term, noise-free performance. The M1 mounts body-up for a clean, purposeful appearance under the lifted chassis.
