Rancho RS5000X 0″ Lift Shocks for 1999-2004 Ford F-550

Part Number: RS55267

Summary: The Rancho RS5000X series provides a significant upgrade for the 1999-2004 Ford F-550, utilizing a sophisticated twin-tube gas-pressurized design to enhance ride quality. Engineered with Rancho’s CrossTune Technology, these shocks manage the heavy-duty demands of a Super Duty chassis by balancing firm control with daily driving comfort. Whether your F-550 is a dedicated work truck or a high-mileage hauler, this complete set ensures consistent damping and reduced harshness over varied terrain.

Features

• CrossTune Technology: A unique progressive engagement valving system provides a custom-tuned feel to ensure stability during towing while maintaining comfort on empty commutes.
• Nitrogen Gas Charge: High-pressure gas displacement provides reduced aeration and foaming to ensure consistent damping performance under heavy loads.
• 9/16-inch Nitro-Carburized Rod: A hardened piston rod provides increased structural rigidity and corrosion resistance to ensure a long service life in harsh environments.
• Protective Boot: A heavy-duty red polyvinyl accordion boot provides a physical barrier for the oil seal to ensure debris does not cause premature leaking.
