M1 Monotube Rear Shock

Conquer rugged trails and city streets with confidence using Rough Country's Nitrogen-Charged M1 Monotube Shock Absorber. Engineered for exceptional ride quality and long-lasting performance, the M1 sets the standard for durability and precision. Featuring an advanced internal floating piston design, the M1 separates shock oil from high-pressure nitrogen, ensuring lightning-fast responsiveness and eliminating cavitation. Every bump, turn, and obstacle is met with unrelenting vibration damping, keeping your ride smooth no matter the challenge. Built to last, the M1 showcases a brushed and galvanized steel body with passivation sealing technology, providing superior protection against the harshest elements. At its core, a 46mm digressive piston ensures uncompromising strength and performance for years to come. Key features include a 2-inch seamless extruded tube for extreme off-road durability, a 46mm digressive piston for precise damping control, self-adjusting deflective-disc technology for smooth rebound and compression, and an 18mm case-hardened, chrome-plated rod to resist wear. The M1 is designed for more than just functionality; its body-up mounting adds a striking, custom look to your vehicle. The 46mm monotube design ensures fade-free performance, while digressive valving reacts instantly to changing trail surfaces for maximum control. A zinc-plated finish protects against mud, water, and harsh off-road environments, and durable vulcanized rubber bushings absorb shock and vibrations. These rear shocks are available in multiple lift heights to match your off-road build and clearance needs. This product is sold in pairs and comes with a 3-year manufacturer's warranty. Installation time is estimated at 1-2 hours. The M1 Monotube Rear Shocks are designed to fit the 2007-2024 Chevrolet Silverado 1500 (2WD and 4WD) and 2007-2024 GMC Sierra 1500 (2WD and 4WD), including specific 2019 Limited and LD models.
