Part Number: RS55610

Summary: The Rancho RS5000X series utilizes a patented progressive rebound and compression disc system to significantly improve handling and ride quality on your lifted truck. Specifically configured for 4-inch lift applications, these shocks bridge the gap between rugged off-road durability and refined street comfort. The twin-tube gas pressurized design ensures a consistent ride by reducing aeration, making it an ideal solution for daily drivers that encounter varied terrain.

Features

• Cross-Tuned Technology: A unique valve calibration system provides a custom-tuned ride experience to ensure stability during high-velocity impacts.
• Nitrogen Gas Charging: Pressurized gas displacement provides a quicker response time to ensure the tires maintain contact with the road surface.
• Protective Boot: A durable polyvinyl accordion boot provides a shield for the shock rod to ensure long-term seal integrity against debris.
• Progressive Engagement: Specialized internal valving provides a smooth transition between damping forces to ensure driver comfort during low-speed crawling.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically lengthened and valved to function correctly on vehicles already equipped with a 4-inch suspension lift.

What is the benefit of the RS5000X gas charging?
The nitrogen gas charge minimizes the foaming of the shock oil (aeration), which prevents shock fade during repetitive cycling on rough roads.

Do I need to purchase boots separately?
No, these Rancho RS5000X shocks include protective polyvinyl boots to keep the piston rod safe from rocks, mud, and road salt.
