Rancho RS5000X 0″ Lift Shocks for 2005-2006 Ford F-550

Part Number: RS55042 / RS55116

Summary: The Rancho RS5000X series is engineered to provide a significant upgrade in ride quality and durability for the Ford F-550. Utilizing a specialized twin-tube gas-pressurized design, these shocks are built to handle the rigorous demands of work and heavy-duty hauling while maintaining a smooth street feel. By incorporating Rancho’s Cross-Tuned technology, they effectively mitigate harsh impacts and vibrations, ensuring your vehicle remains composed under various load conditions at stock height.

Features

• Cross-Tuned Technology: A unique valve system provides a progressive engagement to ensure consistent damping across varying terrain and speeds.
• Gas-Pressurized Twin-Tube: High-pressure nitrogen gas charge provides reduced aeration and foaming to ensure stable performance during heavy-duty cycles.
• Full-Displaced Valving: Precision-tuned internal valving provides better control of compression and rebound to ensure improved handling for 1-ton+ chassis.
• Protective Boot: Included polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against road debris.
