The Monroe® Magnum™ shock absorber for Class 6-8 Vehicles is the first gas-charged, large-bore shock specifically designed for air spring and taper leaf suspensions. Its nitrogen gas charge provides the fast response essential for today's heavy truck suspension systems. Its extra-large piston bore is engineered to handle the demands of high mileage and severe use. When combined, the gas charge and large-bore provide the consistent control necessary for demanding truck suspensions
