Sale Price$129.95
Description : Unmatched Performance: Conquer any terrain with confidence - Rough Country's Nitrogen-Charged M1 Monotube Shock Absorber delivers superior ride quality and performance mile after mile. Engineered for excellence, the M1 features an internal floating piston that keeps shock oil and high-pressure nitrogen separate, ensuring lightning-fast response with zero cavitation for unshakable vibration damping over every obstacle. Built to Last: Crafted for the toughest conditions, the M1 s 2-inch seamless extruded tube offers superior strength, while the 46mm digressive piston provides long-lasting durability and precise control. Digressive valving reacts instantly to changing surfaces, adapting seamlessly to rough trails and smooth streets alike. Engineered for Strength: The 18mm centerless-ground, case-hardened, chromed, and super-polished piston rod enhances durability, while a zinc-plated finish provides exceptional resistance against rust and harsh elements. No matter the conditions, the M1 is built to withstand the test of time. Bold Looks, Smooth Ride: Designed for both performance and aesthetics, the M1 is meant to be mounted body-up for a bold, eye-catching look. Plus, with durable vulcanized natural rubber bushings, you get a smooth, quiet ride with reduced vibrations. Guaranteed Confidence: Backed by Rough Country's 3-year Manufacturer s Warranty, the M1 Monotube Shock Absorber isn t just an upgrade - it s the ultimate performance shock built to handle whatever the road throws your way.
