Description:

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

  • For Hardworking Commercial Vehicles: Designed for high mileage and severe use class 6-8 trucks and buses.

  • 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).

  • 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.
