Keep hardworking class 6-8 trucks and buses planted through high mileage and severe service with the Monroe Magnum Suspension Shock Absorber 65468. It's a direct-fit replacement for the 1997-2002 Isuzu FSR and FVR, the 2011-2017 Peterbilt 382, and the 2022 Peterbilt 536, and Monroe catalogs it as a front or rear suspension shock depending on the application. Monroe built the Magnum as the first gas-charged, large-bore shock for air spring and taper leaf suspensions, and its nitrogen gas charge delivers the fast response heavy-duty truck suspensions demand while helping maintain tire-to-road contact by reducing aeration and shock fade.
- 10-stage valving: tuned to each vehicle and paired with a larger 1-3/4-in. bore for more efficient damping control on most applications.
- All-weather fluid: special additives help handle temperature extremes and reduce oil breakdown, while a larger 2-3/8-in. reserve tube holds more fluid on most applications.
- Strong and durable: a shouldered bushing and a bonded bushing with sleeve protect against bushing walkout, backed by arc welds up to 360°.
- Built to last: a robust hydraulic lock-out helps prevent over-extension of air bags, piston top-out and seal damage on most applications, and a PTFE-coated bearing with a nitrocarburized piston rod reduces friction for longer service life.
Designed to reduce noise, vibration and harshness under most driving conditions, and backed by Monroe's 90-day Risk Free Ride Offer and Limited Commercial Warranty. Sold individually; replacing both shocks on an axle as a matched pair is recommended for balanced ride control.
