Product Details

Monroe Magnum RV Load Adjusting Shock Absorber 555020 is part of the Magnum RV load-adjusting line, a Monroe product line focused on heavier-duty RV and towing use. This shock absorber is specified with an upper S5 stem mount and a lower LS38 loop bushing and sleeve mount, along with a 1/2 in. sleeve ID and 1.5 in. sleeve OAL at the lower end. It is a rear suspension shock absorber for Ford E-350 Econoline and Ford E-350 Econoline Club Wagon models listed for towing and hauling service.

This part cross-references Monroe Shocks & Struts (e.g., 5001331, HD12940004) for the same application.

What It Helps Address

• Excessive rear suspension bounce when carrying cargo or towing
• Reduced damping control on drive axle applications
• Harsh or unsettled ride over uneven road surfaces
• Wear from repeated load cycling in RV and hauling use
• Need for a direct-fit rear shock for the listed Ford E-350 applications

Installation Notes and Tips

Verify compressed length, extended length, and mounting codes before installation. This shock uses a stem upper mount and a loop bushing lower mount, so confirm the vehicle’s existing hardware and mounting style match the listed specifications. Fitment includes 1975-1991 Ford E-350 Econoline, rear, and 1977-1991 Ford E-350 Econoline Club Wagon, rear, with towing and hauling notes on the drive axle.

Quality Assurance

Monroe engineers the Magnum RV line with gas-charged construction and full displaced valving to support controlled suspension response in heavier-duty rear applications. Part number 555020 is built to the published dimensions and mounting configuration for the listed Ford E-350 fitments.
