The Monroe Magnum 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 todays heavy truck suspension systems.

• FOR HARDWORKING COMMERCIAL VEHICLES -- Designed to handle the demands of high mileage and severe use class 6-8 trucks and buses
• CONSISTENT RIDE -- All-weather fluid contains special additives to assist with extreme temperatures and help reduce oil breakdown while larger 2-3/8-in. reserve tube holds more fluid to improve performance (most applications)
• EXCEPTIONAL HANDLING -- 10-Stage valving, tuned specifically to each vehicle, adjusts to road extremes while the larger 1-3/4-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
• BUILT TO LAST -- Robust hydraulic lock-out prevents over extension of air bags, top-out of the piston and averts damage to seal assembly (most applications)
