Monroe 34761 Shock Absorber - Rear

Monroe Gas-Magnum Rear Shock Absorber

Monroe Gas-Magnum Shock Absorber 34761 is built for rear suspension service on Ford E-350 Super Duty, E-150, E-250, and related Econoline applications. It is tuned for firm control with a ride quality that avoids unnecessary harshness, making it a practical choice for heavier vans and trucks that need stable damping.

The Gas-Magnum line is Monroe’s heavy-duty shock absorber family for midsize and full-size trucks and vans. This Monroe 34761 uses increased fluid capacity to manage heat and repeated suspension movement more efficiently than a standard 1-inch bore design.

Detailed Description

Monroe 34761 is a rear suspension shock absorber engineered for vehicles that regularly carry weight or see frequent road input. The Gas-Magnum shock absorber design uses greater fluid capacity to improve efficiency under load, helping maintain consistent damping on Ford E-350 Super Duty, E-150, E-250, E-150 Econoline, E-250 Econoline, and E-350 Econoline rear suspension setups. If you are replacing a worn rear shock on a Ford E-350 Super Duty or Ford E-250, this part number provides a direct service option for the listed applications.

This part cross-references Monroe Shocks & Struts 172286 and 182286 for the same application.

What It Helps Address

• Excessive rear bounce after bumps or dips
• Reduced control from worn rear shock absorbers
• Unstable ride quality in heavier van and truck use
• Suspension movement that feels loose or underdamped
• Heat-related fade from repeated shock cycling

Installation Notes and Tips

Verify rear fitment by matching the vehicle year, model, and mounting style before installation. Monroe 34761 uses a stem upper mount and a loop bushing lower mount, so the existing hardware and mounting points should be inspected for wear, corrosion, or damage during replacement. Confirm compressed length, extended length, and travel length against the original shock absorber to ensure proper suspension travel on the Ford E-350 Super Duty, E-150, or E-250 application.

Quality Assurance

Monroe backs this shock absorber with a limited lifetime warranty on the listed applications. The Gas-Magnum line is positioned for heavy-duty truck and van service, with construction focused on controlled damping and durable operation in rear suspension use.
