- Nitrogen gas-charged: Maintains tire-to-road contact by reducing aeration and shock fade for improved ride and handling.
- 10-Stage valving: Tuned specifically to each vehicle to adjust to road extremes, while a larger 1-3/8-in. bore provides more efficient damping control on most applications.
- All-weather fluid: Special additives assist with extreme temperatures and help reduce oil breakdown; a 2-in. or 2-1/4-in. reserve tube holds more fluid when required.
- Strong and durable: Shouldered and bonded bushing with sleeve helps protect against bushing walkout, arc welds run up to 360°, and a robust hydraulic lock-out helps prevent over-extension on most applications.
Designed to handle the demands of high-mileage, severe-use class 3-6 trucks and buses, the Magnum helps reduce excessive vibration when worn units are replaced. Excessive vibration, bouncing, or reduced control can be signs your shocks may need replacing. Backed by Monroe's 90-day Risk Free Ride Offer and Limited Commercial Warranty.
