The Monroe® Magnum® Front Suspension Shock Absorber for class 6-8 vehicles is the first gas-charged, large-bore shock designed for air spring and taper leaf suspensions. The nitrogen gas charge provides the fast response essential for today's heavy-duty truck suspension systems.

Built for severe use class 6-8 trucks, the Magnum front shock delivers consistent performance for Western Star 3800 and 6900XD platforms with its large-bore design and 10-stage valving.

• FOR HARDWORKING COMMERCIAL VEHICLES: Designed to handle high mileage and severe use class 6-8 trucks and buses.
• CONSISTENT RIDE: All-weather fluid handles extreme temperatures; larger 2-3/8-in. reserve tube holds more fluid (most applications).
• EXCEPTIONAL HANDLING: 10-Stage valving tuned to each vehicle; larger 1-3/4-in. bore for efficient damping (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: Exceptional control isolating NVH under most driving conditions.
• IMPROVES PERFORMANCE: Nitrogen gas-charge reduces aeration and shock fade.
