The Monroe® Magnum® Rear Suspension Shock Absorber for class 3-6 vehicles is gas-charged for quicker response and a stable, more comfortable ride. Designed for high mileage and severe use vehicles, it replaces worn units to help reduce excessive vibration.

A wide-coverage rear Magnum shock for Mack, Hino, and Ford B-Series and F-Series commercial trucks, 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 class 3-6 trucks and buses.
• Consistent Ride: All-weather fluid with special additives handles extreme temperatures; 2-in. or 2-1/4-in. reserve tube holds more fluid (when required).
• Exceptional Handling: 10-Stage valving tuned per vehicle; larger 1-3/8-in. bore for more efficient damping and a smoother ride (most applications).
• Strong and Durable: Shouldered and bonded bushing with sleeve prevents bushing walkout; arc welds up to 360° for durability.
• Built to Last: Hydraulic lock-out prevents over-extension of air bags and protects the seal assembly (most applications).
• Longer Service Life: PTFE-coated bearing and nitrocarburized piston rod for durability and extended service life (most applications).
• Reduced NVH: Isolates 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.
