Description:

The Monroe® Magnum® Front and 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.

This multi-position Magnum shock covers Mack, Kenworth, Peterbilt, and Spartan Motors platforms across front and rear applications, 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 6-8 trucks and buses.
  • Consistent Ride: All-weather fluid with special additives handles extreme temperatures; larger 2-3/8-in. reserve tube holds more fluid (most applications).
  • Exceptional Handling: 10-Stage valving tuned per vehicle; larger 1-3/4-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: 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.
