$66.00 CAD

Magnum Shock Absorber
Magnum Front Suspension Shock Absorber
Monroe Magnum 66903 Front Suspension Shock Absorber
BUY WITH CONFIDENCE -- Comes with Monroe’s 90-day Risk Free Ride Offer and Limited Commercial Warranty
EXCEPTIONAL HANDLING -- 10-Stage valving, tuned specifically to each vehicle, adjusts to road extremes while the larger 1-3/8-in. bore provides more efficient damping control to provide consistency and a smooth ride (most applications)
STRONG AND DURABLE -- Shouldered bushing and bonded bushing with sleeve protects from bushing walkout for improved quality; arc welds up to 360° for durability
FOR HARDWORKING COMMERCIAL VEHICLES   -- Designed to handle the demands of high mileage and severe use class 3-6 trucks and buses
IMPROVES PERFORMANCE -- Nitrogen gas-charge maintains tire-to-road contact for improved ride and handling by reducing aeration and shock fade
LONGER SERVICE LIFE -- Bearing with PTFE coating reduces friction between rod and rod guide combined with nitrocarburized piston rod provides durability and longer service life (most applications)
CONSISTENT RIDE -- All-weather fluid contains special additives to assist with extreme temperatures and help reduce oil breakdown while 2-in. or 2-1/4-in. reserve tube holds more fluid to improve performance (when required)
REDUCED NOISE, VIBRATION AND HARSHNESS -- Delivers exceptional control and isolates impact-related noise, vibration, and harshness under most driving conditions
BUILT TO LAST -- Robust hydraulic lock-out prevents over extension of air bags, top-out of the piston and averts damage to seal assembly (on most applications)
The Monroe® Magnum® shock absorber for class 3-6 vehicles is gas-charged for quicker response and a stable, more comfortable ride. Designed to handle the demands of high mileage and severe use vehicles, replace worn-out units with Magnum® shocks to help reduce excessive vibration.
