Rancho RS5000X 4″ Front Lift Shocks for 1999-2007 GMC Sierra 1500 4WD

Part Number: RS55268

Summary: The Rancho RS5000X series utilizes a sophisticated twin-tube gas pressure design to provide a significant upgrade in ride quality and durability for your lifted GMC. Engineered specifically to handle the increased leverage of a 4-inch lift, these shocks feature a unique cross-tuned valve system that balances on-road smoothness with off-road control. The robust twin-tube construction provides excellent dent resistance, ensuring that even if the outer body is damaged by debris, the internal piston remains functional for consistent performance.

Features

• Cross-Tuned Technology: A specialized valve system provides a progressive damping curve to ensure a smooth street ride and controlled off-road handling.
• Twin-Tube Gas Pressure: The 1.375-inch internal piston diameter provides increased fluid capacity to ensure consistent performance and reduced fade during cycling.
• Nitro-Carburized Piston Rod: A heavy-duty finished rod provides superior corrosion resistance to ensure long-term seal integrity in harsh environments.
• Protective Boot Included: A durable red polyvinyl accordion boot provides a physical barrier for the rod and oil seal to ensure longevity against road grime and debris.

Frequently Asked Questions

Does this shock provide the 4 inches of lift?
No, these shocks do not create lift. They are specifically valved and length-matched for vehicles already equipped with a 4-inch suspension lift kit.

What is the benefit of the Twin-Tube design?
The twin-tube design is highly durable for daily driving and light off-roading; the outer tube protects the inner working cylinder from rock chips and dents.

Are these sold as a pair?
Yes, this SKU (2xRS55268) includes a pair of front shocks to complete the front axle of your vehicle.
