Summary: The Rancho RS5000X series leverages advanced CrossTune technology to provide a refined ride for your GMC K2500 4WD. Engineered with a large 2.25-inch reserve tube, these shocks are designed to handle the increased demands of vehicles with 2.5 to 4 inches of lift. By utilizing a unique valving system, the RS5000X delivers a smooth street feel while maintaining the durability required for light off-road use and towing.

Features

• CrossTune Technology: A unique base valve design provides a progressive engagement throughout the piston stroke to ensure consistent control across varying terrains.
• Twin-Tube Design: A 2.25-inch outer reserve tube provides increased fluid capacity to reduce internal temperatures and ensure fade-free performance during heavy-duty use.
• Nitro-Gas Charge: High-pressure nitrogen gas provides a rapid response rate to ensure the tires maintain contact with the road surface.
• Protective Boot: A durable polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against debris.

Frequently Asked Questions

Will these shocks lift my GMC K2500?
No, these shocks do not provide lift. They are specifically valved and extended to accommodate vehicles already equipped with a 2.5″ to 4″ suspension lift.

What is the benefit of the twin-tube design?
The twin-tube construction allows for a larger oil capacity and makes the shock more resistant to external damage; even if the outer tube is dented, the inner pressure tube remains functional.

Do these shocks include the mounting hardware?
Yes, this set includes all necessary bushings and sleeves required for an OE-style installation on the GMC K2500 4WD.
