Rancho RS5000X 4″ Lift Shocks for 2001-2010 GMC Sierra 2500HD

Part Number: RS55289

Summary: The Rancho RS5000X series leverages advanced Cross-Tuned technology to provide a significant upgrade in ride quality for lifted heavy-duty trucks. Designed specifically for vehicles with a 4-inch lift, these shocks utilize a gas-pressurized twin-tube design to deliver exceptional durability and dent resistance during off-road use. By minimizing aeration and foaming, the RS5000X ensures a smooth, controlled street ride while maintaining the ruggedness required for demanding work or trail environments.

Features

• Cross-Tuned Technology: A unique valve system provides a custom-tuned compression and rebound cycle to ensure consistent handling on uneven terrain.
• Twin-Tube Body: A 2.25-inch reserve tube provides increased fluid capacity to ensure cooler operation and sustained damping performance.
• Nitrogen Gas Pressurization: High-pressure gas charge provides a quicker response time and reduced aeration to ensure fade-free performance.
• Protective Boot: A durable poly-vinyl 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 truck?
No, these shocks do not create lift. They are specifically valved and length-configured for vehicles already equipped with a 4-inch suspension lift.

What is the benefit of the twin-tube design?
The twin-tube design offers an outer reserve tube that protects the inner working cylinder from dents, ensuring that off-road debris doesn’t cause shock failure.

Do I need to purchase boots separately?
No, this set includes Rancho’s signature red protective boots to keep the piston rods clean and clear of contaminants.
