Product Details

The Monroe Gas-Magnum line is engineered for heavier-duty truck and van suspension demands, and part number 34770 follows that approach with a larger fluid capacity than standard 1-inch bore shocks. That extra capacity helps the shock work more efficiently with less effort, which is important on rear suspension setups for Ford F-250 Super Duty and Ford F-350 Super Duty models. This part cross-references Rancho RS55046 for the same application.

Use Monroe 34770 when you need a rear shock absorber that supports controlled ride motion without adding unnecessary harshness. It is a direct fit for 2005-2016 Ford F-250 Super Duty, rear, and 2005-2016 Ford F-350 Super Duty, rear.

Common Issues This Part Can Address

• Excessive rear-end bounce over uneven pavement
• Reduced control during load changes or towing
• Rear suspension instability on rough roads
• Worn shock response from age and mileage
• Loss of damping consistency in heavy-duty truck use

Installation Notes and Tips

Verify upper and lower mounting styles before installation: loop bushing mount at the top and loop bushing with sleeve mount at the bottom. Confirm compressed and extended lengths against the vehicle’s suspension travel to ensure proper fitment on the rear of the Ford F-250 Super Duty or Ford F-350 Super Duty. Inspect surrounding bushings and mounting points during replacement.

Monroe Gas-Magnum shock absorbers are built for truck and van suspension service, with a design focused on efficient damping and controlled ride quality. Fitment is listed for 2005-2016 Ford F-250 Super Duty and Ford F-350 Super Duty rear applications.
