- Gas-charged design: Nitrogen gas-charge helps maintain tire-to-road contact by reducing aeration and shock fade for improved ride and handling.
- Built for severe use: Designed to handle the demands of high-mileage, severe-use class 3-6 trucks and buses; replace worn units to help reduce excessive vibration.
- Consistent damping: 10-stage valving tuned to the vehicle adjusts to road extremes, and a larger 1-3/8 in. bore provides more efficient damping control on most applications.
- Durable construction: Shouldered and bonded bushing with sleeve protects against bushing walkout, with arc welds up to 360° for durability.
All-weather fluid with special additives helps resist oil breakdown at extreme temperatures. If worn rear shocks are causing excessive vibration or a harsh ride on your NV, this Magnum unit replaces them. Backed by Monroe's 90-Day Risk Free Ride Offer and Limited Commercial Warranty.
