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 comprehensive cab replacement for Freightliner and Western Star conventional and sleeper cab trucks, the Magnum Cab shock is 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.
