Monroe Gas-Magnum Shock Absorber - 66721

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.

• 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)
• 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
• CONSISTENT RIDE -- All-weather fluid contains special additives to assist with extreme temperatures and help reduce oil breakdown while 2 inch or 2-1/4 inch reserve tube holds more fluid to improve performance (when required)
• STRONG AND DURABLE -- Shouldered bushing and bonded bushing with sleeve protects from bushing walkout for improved quality
• arc welds up to 360 degree for durability
• 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)
• EXCEPTIONAL HANDLING -- 10-Stage valving, tuned specifically to each vehicle, adjusts to road extremes while the larger 1-3/8 inch bore provides more efficient damping control to provide consistency and a smooth ride (most applications)
• REDUCED NOISE, VIBRATION AND HARSHNESS -- Delivers exceptional control and isolates impact-related noise, vibration, and harshness under most driving conditions
