Summary: The Rancho RS5000X series utilizes a cross-tuned twin-tube gas pressurized design to provide an immediate upgrade in ride quality for your heavy-duty truck. Engineered to eliminate the harshness often found in factory dampers, these shocks feature a unique progressive engagement valving system that adapts to varying road conditions. Whether navigating highway expansion joints or maintaining stability under load, these shocks provide the durability and dent resistance required for work-ready vehicles.

Features

• Cross-Tuned Technology: A specialized twin-tube valving system provides increased fluid capacity to ensure consistent cooling and reduced fade during heavy use.
• Progressive Engagement Valving: Custom-tuned internal discs provide a smooth transition between low and high-speed impacts to ensure driver comfort without sacrificing vehicle control.
• Nitro-Carburized Piston Rod: A heavy-duty 16mm diameter rod provides superior scuff resistance and corrosion protection to ensure a long service life in harsh environments.
• Gas Pressurized Design: High-pressure nitrogen charging provides a reduction in oil foaming and aeration to ensure immediate response and consistent damping force.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks are configured for 0″ of lift and are designed to replace the factory-length dampers. They do not provide lift height themselves.

What is the benefit of the twin-tube design?
The twin-tube design is exceptionally durable; if the outer body is dented by road debris, the inner working tube remains unaffected, ensuring the shock continues to function properly.

Are these sold as a pair?
Yes, this specific SKU (2xRS55120) includes two front shocks to complete the front axle of your vehicle.
