Rancho Steering Stabilizer for 2008-2013 Ford F-550 Superduty 4WD

Part Number: RS5415

Summary: The Rancho RS5000 series steering stabilizer is engineered to enhance the handling characteristics of your Ford F-550 Super Duty by reducing wheel shimmy and steering vibration. Utilizing a heavy-duty twin-tube construction, this stabilizer provides consistent damping and extra protection against trail debris. It is specifically configured for 4WD applications to improve driver control and reduce fatigue during long hauls or off-road excursions.

Features

• Twin-Tube Body: A 2-inch diameter cellular gas-pressurized body provides increased fluid capacity to ensure cooler operation and consistent damping performance.
• Protective Boot: The included red polyvinyl accordion boot provides a physical barrier for the shock rod to ensure protection against dirt, moisture, and road grime.
• Hardened Piston Rod: A 1/2-inch nitro-carburized piston rod provides structural rigidity and corrosion resistance to ensure a long service life in harsh environments.
• All-Weather Fluid: Specialized high-temperature oil provides reduced friction and consistent viscosity to ensure smooth steering response across extreme temperature ranges.

Frequently Asked Questions

Will this steering stabilizer fix “Death Wobble”?
While a new stabilizer can help dampen vibrations, it is often a mask for worn suspension components. We recommend inspecting your track bar and ball joints if you are experiencing severe oscillation.

Does this unit replace the factory stabilizer?
Yes, the RS5415 is designed as a direct-fit replacement for the original equipment (OE) stabilizer on the 2008-2013 Ford F-550 4WD.

Is the protective boot required for installation?
While the stabilizer will function without it, the boot is highly recommended to protect the piston rod from pitting and debris, which extends the life of the internal seals.
