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.

  • For Hardworking Commercial Vehicles: Designed for high mileage and severe use class 3-6 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).
  • 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.
