Rancho RS5000X 4″ Rear Lift Shocks for 2002-2006 Chevy Avalanche 2500

Part Number: RS55297

Summary: The Rancho RS5000X series utilizes an innovative cross-tuned twin-tube design to provide a significant upgrade in ride quality for lifted applications. Engineered to handle the increased demands of a 4-inch lift, these shocks feature a unique valving system that minimizes foaming and aeration. This ensures consistent damping performance and smooth street comfort whether you are navigating daily commutes or moderate off-road trails.

Features

• Cross-Tuned Technology: A specialized valve base provides a progressive engagement to ensure smooth transitions between varying terrain types.
• Gas Pressurization: High-pressure nitrogen gas provides reduced aeration and foaming to ensure consistent hydraulic performance under load.
• Protective Boot: The included polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against debris.
• Heavy-Duty Body: The 2.25-inch reserve tube provides increased fluid capacity to ensure cooler operating temperatures during extended use.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically configured for vehicles already equipped with a 4-inch rear lift kit to ensure the piston operates within its optimal travel range.

What is the benefit of the RS5000X gas pressurization?
The nitrogen gas charge keeps the internal hydraulic fluid under pressure, which prevents the oil from foaming during rapid cycling, maintaining consistent damping force.

Are these sold as a pair?
Yes, this SKU (2xRS55297_n11) includes a pair of two rear shocks.
