Summary: The Rancho RS5000X series features a patented progressive rebound and compression disc system that significantly improves on-road handling and off-road ruggedness. Designed for drivers who demand durability, these twin-tube gas-pressurized shocks provide excellent dent resistance and a smooth street ride. Configured for 1-2.5 inches of front lift, they serve as a high-performance upgrade for leveled or mildly lifted heavy-duty trucks and SUVs.

Features

• Cross-Tuned Technology: A unique valve arrangement provides specific damping curves to ensure a balanced ride across varying terrain.
• Twin-Tube Design: A 2.25-inch diameter outer tube provides increased oil capacity and physical protection to ensure consistent performance even if the outer body is dented.
• Gas Pressurization: Low-pressure nitrogen gas charge provides reduced aeration and foaming to ensure immediate response and fade resistance.
• Protective Boot: Included polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity in harsh environments.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically configured and valved to accommodate vehicles already equipped with 1 to 2.5 inches of front suspension lift.

What is the benefit of the RS5000X twin-tube design?
The twin-tube design is highly durable for off-road use; if the outer shell is dented by a rock or debris, the inner working tube remains unaffected, allowing the shock to continue functioning.

Can I use these with my factory shock spacers?
No, these shocks are not for use with aftermarket shock spacers or relocation brackets as it may exceed the designed travel limits of the unit.
