Rancho RS5000X 0″ Rear Lift Shocks for 1999-2004 Ford F-450

Part Number: RS55126

Summary: The Rancho RS5000X series utilizes a cross-tuned twin-tube design to significantly improve the ride quality of your Ford F-450. Engineered with a unique progressive engagement valving system, these shocks provide a smooth, comfortable street ride while maintaining the necessary control for heavy-duty hauling. Designed for stock height applications, they offer a durable solution for drivers seeking to eliminate the harshness often associated with heavy-duty work trucks.

Features

• Progressive Engagement Valving: A custom-tuned internal shim stack provides increased control during high-velocity impacts to ensure a smooth transition between various road surfaces.
• Twin-Tube Gas Pressure Cell: The nitrogen gas-charged 2.25-inch body reduces aeration and foaming provides consistent damping performance to ensure reliable handling under load.
• Glass-Filled Fluoro-Ethylene Band: A specialized piston seal provides a friction-reduced interface between the piston and pressure tube to ensure long-term durability and instantaneous response.
• Protective Boot Included: A high-quality polyvinyl accordion boot provides a physical barrier for the piston rod to ensure the oil seal remains free from debris and contaminants.
