Summary: The Rancho RS5000X series utilizes an innovative cross-tuned twin-tube design to provide a significant upgrade over factory damping for the US Postal FJ-9.

• Gas Pressurization: Nitrogen gas charging provides a consistent damping force to ensure reduced fade during extended operation.
• 16mm Nitro-Carburized Rod: A heavy-duty hardened piston rod provides superior corrosion resistance to ensure a long service life in harsh environments.
