Rancho RS5000X 4″ Rear Lift Shocks for 1988-2000 Chevy K3500 4WD

Part Number: RS55227

Summary: The Rancho RS5000X series leverages a cross-tuned twin-tube design to provide a significant upgrade in ride quality for lifted heavy-duty applications. Engineered specifically for the Chevy K3500 and GMC Yukon, these shocks utilize a unique progressive engagement valving system to minimize harshness during initial impacts. This gas-pressurized solution is designed to handle the increased unsprung weight of larger tires while maintaining smooth street comfort and off-road durability.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition between damping circuits to ensure a smooth ride over small road imperfections.
• Gas Pressurization: Nitrogen gas charging provides consistent pressure against the internal oil to ensure reduced aeration and shock fade during heavy use.
• Enlarged 2.25-inch Body: A high-capacity twin-tube outer housing provides increased oil volume to ensure cooler operating temperatures and dent 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 truck?

The twin-tube design is highly durable; even if the outer body is dented by road debris, the internal piston remains functional, ensuring you aren’t stranded.

Yes, based on the SKU configuration, this package includes 2 rear shocks.
