Part Number: RS55116

Summary: The Rancho RS5000X series leverages advanced CrossTune technology to significantly improve the ride quality of your Plymouth PB-series van. Designed as a high-performance twin-tube upgrade, these shocks feature a unique valving system that balances on-road comfort with off-road durability. By utilizing a larger 2.25-inch reserve tube, the RS5000X provides increased oil capacity to maintain consistent damping performance under heavy loads or varying road conditions.

Features

• CrossTune Technology: A progressive engagement valving system provides a custom-tuned ride to ensure precise control during both low-speed maneuvers and high-speed impacts.
• Gas Pressurization: High-pressure nitrogen gas charge provides a quicker response time to ensure reduced aeration and foaming.
• 2.25-inch Reserve Tube: An oversized fluid body provides greater heat dissipation to ensure consistent damping performance during extended use.
• Nitro-Carburized Piston Rod: A heavy-duty 16mm rod construction provides superior corrosion resistance to ensure long-term seal integrity in harsh environments.
