Product Details

This Monroe Reflex Light Truck Shock Absorber 911173 is engineered for front suspension control on 1999-2021 Ford F-250 Super Duty, 1999-2021 Ford F-350 Super Duty, and 2000-2005 Ford Excursion models. The Reflex Light Truck Shock Absorber line focuses on managing roll and dive in trucks and SUVs with a higher center of gravity, helping the suspension respond more consistently during braking, cornering, and uneven pavement. This part cross-references Rancho RS55272 for the same application.

What It Helps Address

• Excessive front-end dive during braking
• Body roll in tall trucks and SUVs
• Harsh response over broken pavement and expansion joints
• Reduced control from worn front shocks
• Uneven ride quality at the front suspension

Installation Notes

Verify front suspension fitment by year, model, and mounting style before installation. Confirm the stem mount upper connection and loop bushing lower connection match the vehicle’s original shock configuration. Inspect surrounding suspension components, bushings, and mounts for wear before replacing the shock absorber.
