Rancho RS5000X 2.5-4″ Front Lift Shocks for 1988-2000 GMC K2500 4WD

Part Number: RS55001

Summary: The Rancho RS5000X series utilizes a cross-tuned twin-tube design to provide a significant upgrade in ride quality for lifted GMC K2500 and Yukon applications. Engineered to handle the increased leverage of a 2.5-4 inch lift, these shocks feature a unique valving system that minimizes harshness over small bumps while maintaining firm control during heavy compression. The gas-pressurized twin-tube construction ensures long-term durability and dent resistance, making it an ideal solution for daily driven trucks that see occasional off-road use.

Features

• Cross-Tuned Technology: A specialized valve base provides a progressive engagement to ensure smooth transition between street comfort and off-road control.
• Twin-Tube Construction: The 2.25-inch reserve tube provides increased oil capacity to ensure consistent cooling and shock performance during extended use.
• Nitro-Carburized Piston Rod: A heavy-duty 16mm rod diameter provides superior structural strength to ensure longevity against pitting and corrosion.
• All-Weather Fluid: Specialized friction-reducing modifiers provide consistent damping performance in temperatures ranging from -40 to 248 degrees Fahrenheit to ensure reliable handling in any climate.

Frequently Asked Questions

Will these shocks lift my GMC truck?
No, these shocks do not create lift. They are specifically configured with the correct extended and compressed lengths to work with vehicles already equipped with a 2.5-4 inch suspension lift.

What is the benefit of the RS5000X twin-tube design?
The twin-tube design is highly durable for trucks; if the outer tube is dented by a rock or debris, the inner working tube remains functional, ensuring you aren’t left stranded.

Are boots included with these shocks?
Yes, this pair includes Rancho’s signature red protective boots to keep the piston rods clean and free of debris.
