Summary: The Rancho RS5000X series utilizes an advanced Cross-Tuned technology to provide a significant upgrade over factory damping for your heavy-duty truck. Designed specifically for the Chevy R30 and R3500 2WD Crew Cab, these shocks feature a unique valving system that minimizes foaming and aeration. The twin-tube gas pressurized design ensures consistent performance and durability, providing a smooth, controlled ride for both daily commuting and utility work.

• Gas Pressurization: High-pressure nitrogen gas charge provides a reduction in fluid aeration to ensure consistent performance during heavy hauling.
• Protective Boot: A heavy-duty polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against road debris.
