Smooth out the ride and rein in bounce and body wander with the Monroe Magnum RV Shock Absorber 557007, a rear-position hydraulic shock built for the demands of motorhomes and other recreational vehicles. It's a direct-fit replacement for a long list of RV chassis and coaches, including the 2000-2023 Fleetwood Bounder, 2008-2023 Coachmen Mirada, 1999-2004, 2006-2009 and 2011-2023 Ford F-53 Motorhome Chassis, 2007-2022 Newmar Bay Star, and many more — see the Buyer's Guide tab for the full application list.
- Gas-charged control: Combines a nitrogen gas charge with full displaced valving to help reduce bounce and wander and maintain tire-to-road contact by reducing aeration and shock fade.
- Consistent ride: All-weather fluid with special additives helps handle temperature extremes and reduce oil breakdown, while a larger reserve tube holds more fluid.
- Tuned valving: 10-stage valving tuned to the vehicle adjusts to road extremes, helping isolate impact-related noise, vibration and harshness under most driving conditions (most applications).
- Strong and durable: Shouldered and bonded bushing with sleeve protects against bushing walkout, with arc welds up to 360° for durability.
Backed by Monroe's 90-day Risk Free Ride Offer and Limited Commercial Warranty. Shocks work as a pair on an axle — replacing both sides together is recommended for balanced control.
Frequently Asked Questions
What position does this shock fit?
It is a rear suspension shock absorber for the listed recreational-vehicle applications. Check the Buyer's Guide tab to confirm fitment for your RV.
Is this a gas-charged shock?
Yes. The Magnum RV uses a nitrogen gas charge with full displaced valving to help reduce aeration and shock fade and maintain tire-to-road contact for improved ride and handling.
Does it fit my motorhome?
It's a direct-fit replacement for many RV chassis and coaches, such as the Fleetwood Bounder, Coachmen Mirada, Ford F-53 chassis and Newmar Bay Star. See the Buyer's Guide tab for the full list.
Should I replace both shocks at once?
Shocks work as a pair on an axle, so replacing both sides together is recommended for balanced, even control. This listing covers one shock.
When might this shock need replacing?
Excessive bounce, body wander, poor handling, or fluid leakage can be signs a shock is worn. Have the suspension inspected to confirm the cause before replacing.
