Part Number: RS55379

Summary: The Rancho RS5000X series is engineered to provide a significant upgrade in ride quality and durability for the GMC Sierra 3500HD. Utilizing a sophisticated twin-tube design, these shocks are specifically calibrated to reduce harshness while maintaining the heavy-duty control required for 1-ton trucks. Whether navigating job sites or highway hauling, the gas-pressurized construction ensures consistent damping performance and long-term reliability for stock height applications.

Features

• Crossed Landscape Valve System: Progressive engagement valving provides custom-tuned damping to ensure smooth street comfort and improved control during off-road transitions.
• Gas Pressurization: High-pressure nitrogen charging provides reduced aeration and foaming to ensure consistent performance under heavy load conditions.
• Heavy-Duty Twin-Tube Body: A 2.25-inch reserve tube provides increased fluid capacity to ensure cooler operating temperatures and dent resistance in harsh environments.
• Protective Boot: A durable polyvinyl accordion boot provides a physical barrier for the piston rod to ensure the oil seal remains free of debris and contaminants.

Frequently Asked Questions

Will these shocks lift my GMC Sierra 3500HD?
No, these shocks are configured for 0-inches of lift and do not provide any lift height; they are designed to replace factory-length shocks.

Is this a complete set for the front and rear?
This SKU includes 2 shocks specifically for the rear position of your vehicle.

What is the benefit of the twin-tube design?
The twin-tube design allows for a larger oil reservoir and provides an extra layer of protection, as a dent to the outer tube will not immediately affect the internal piston movement.
