The Monroe® Magnum® Front Suspension Shock Absorber for class 3-6 vehicles is gas-charged for quicker response and a stable, more comfortable ride. Designed to handle the demands of high mileage and severe use vehicles, replacing worn-out units with Magnum® shocks helps reduce excessive vibration.

Purpose-built for class 3-6 trucks and buses, the Magnum delivers gas-charged performance with 10-stage valving and a larger bore for consistent damping. Its durable construction and all-weather fluid make it a reliable choice for commercial fleet operators.

• FOR HARDWORKING COMMERCIAL VEHICLES: Designed to handle high mileage and severe use class 3-6 trucks and buses.
• CONSISTENT RIDE: All-weather fluid handles extreme temperatures; 2-in. or 2-1/4-in. reserve tube holds more fluid (when required).
• EXCEPTIONAL HANDLING: 10-Stage valving tuned to each vehicle; larger 1-3/8-in. bore provides consistent, smooth ride (most applications).
• STRONG AND DURABLE: Shouldered and bonded bushings protect from bushing walkout; arc welds up to 360° for durability.
• BUILT TO LAST: Robust 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 long-lasting durability (most applications).
• REDUCED NOISE, VIBRATION AND HARSHNESS: Delivers exceptional control isolating NVH under most driving conditions.
• IMPROVES PERFORMANCE: Nitrogen gas-charge reduces aeration and shock fade.
• BUY WITH CONFIDENCE: Comes with Monroe's 90-day Risk Free Ride Offer and Limited Commercial Warranty.
