Soak up the bounce, sway and road harshness of life on the highway with the Monroe Magnum RV Shock Absorber 557007, a rear-position damper built for the demands of recreational vehicles. It fits a wide range of motorhome and RV chassis, including the 1999-2004, 2006-2009 and 2011-2023 Ford F-53 Motorhome Chassis, the 2011-2020 Ford F-59 Commercial Stripped Chassis, the 2000-2023 Fleetwood Bounder, the 2008-2023 Coachmen Mirada and the 1999-2017 and 2019-2022 Winnebago Adventurer — see the Buyer's Guide tab for the full list of 59 applications.
- Gas-charged control: A nitrogen gas charge and full displaced valving help reduce bounce and wander, maintaining tire-to-road contact by reducing aeration and shock fade.
- Consistent ride: All-weather fluid with special additives assists in extreme temperatures and helps reduce oil breakdown, while a larger reserve tube holds more fluid to improve performance when required.
- Tuned handling: 10-Stage valving, tuned specifically to each vehicle, adjusts to road extremes, and on most applications the bore provides more efficient, consistent control.
- Strong and durable: A shouldered bushing and a bonded bushing with sleeve help protect against bushing walkout, with arc welds up to 360° for durability.
A robust hydraulic lock-out helps prevent over-extension of air bags, piston top-out and damage to the seal assembly when required. Backed by Monroe's 90-Day Risk Free Ride Offer and Limited Commercial Warranty.
