Damp out excessive vibration and keep heavy-duty suspension travel under control with the Monroe Magnum Suspension Shock Absorber 66710. This gas-charged shock is built for class 3-6 trucks and buses, dropping in as a replacement across a wide commercial lineup — including the 1979-1989 International F2275, F2554 and F2674, the 1981-2002 International 2554, the 1984-2003 International 2574, the 2001-2006 Mack LE and the 2008-2019 Mack MRU. See the Buyer's Guide tab for the full list of applications. The catalog lists this shock for both front and rear positions depending on the vehicle.
Gas-charged design: A nitrogen gas charge helps maintain tire-to-road contact by reducing aeration and shock fade for improved ride and handling.
10-Stage valving: Tuned specifically to each vehicle, with a larger 1-3/8-in. bore for more efficient damping control on most applications.
All-weather fluid: Special additives help handle extreme temperatures and reduce oil breakdown, while a 2-in. or 2-1/4-in. reserve tube holds more fluid when required.
Built to last: A shouldered and bonded bushing with sleeve guards against bushing walkout and arc welds up to 360° add durability, while a PTFE-coated bearing and nitrocarburized piston rod support longer service life on most applications.
Designed for high-mileage and severe-use vehicles, the Magnum isolates impact-related noise, vibration and harshness under most driving conditions. If worn shocks are the cause of a rough, bouncy ride, replacing them with the 66710 helps restore ride control. Backed by Monroe's 90-day Risk Free Ride Offer and Limited Commercial Warranty.
