The Monroe® Magnum® Cab Suspension Shock Absorber is a gas-charged unit designed for heavy-duty cab suspensions, isolating the cab from the frame for a smoother, more comfortable ride. Velocity-sensitive valving delivers a new standard in driver comfort (most applications).

A direct-fit cab replacement for Mack CH and CL series trucks, the Magnum Cab shock reduces driver fatigue and NVH, backed by Monroe's 90-day Risk Free Ride Offer and Limited Commercial Warranty.

• For Hardworking Commercial Vehicles: Designed for high mileage and severe use vehicles with cab suspensions.
• Consistent Ride: All-weather fluid with special additives handles extreme temperatures; larger 2-in. reserve tube holds more fluid (when required).
• Exceptional Handling: 10-Stage valving tuned per vehicle; larger 1-3/8-in. bore provides efficient and consistent control (most applications).
• Strong and Durable: Shouldered and bonded bushing with sleeve prevents bushing walkout; arc welds up to 360° for durability.
• Longer Service Life: PTFE-coated bearing and nitrocarburized piston rod for durability and extended service life (most applications).
• Reduced NVH: Exceptional control isolating impact-related noise, vibration, and harshness under most driving conditions.
• Improves Performance: Nitrogen gas-charge maintains tire-to-road contact by reducing aeration and shock fade.
• Buy with Confidence: Comes with Monroe's 90-day Risk Free Ride Offer and Limited Commercial Warranty.

Common Fits: Mack CH (1989-2005), Mack CL (1991-2007). All fitments are cab position.
