Rancho RS5000X 1.5″ Front Lift Shocks for 1963-1972 GMC C2500 2WD Rear Leaf Spring

Part Number: RS55120

Summary: The Rancho RS5000X series utilizes an innovative cross-tuned twin-tube design to significantly improve the handling and ride quality of your GMC C2500. Specifically configured for 1.5-inch front lift applications, these shocks employ a unique Progressive Engagement Valving system that reduces initial impact harshness. This setup provides a smooth, durable solution for classic trucks with rear leaf springs, ensuring better control both on the street and during light utility work.

Features

• Progressive Engagement Valving: Custom-tuned internal velocity sensors provide a soft ride during normal travel while increasing firmness during sudden impacts to ensure consistent vehicle stability.
• Twin-Tube Gas Pressure: The large 2.25-inch body diameter provides increased fluid capacity to ensure cooler operating temperatures and reduced shock fade.
• Nitro-Carburized Piston Rod: The heavy-duty 16mm rod construction provides superior scuff resistance and protection against corrosion to ensure long-term structural integrity.
• Polyurethane Bushings: High-density mounting points provide enhanced durability and reduced deflection to ensure precise steering response.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically valved and extended to accommodate vehicles that have already been modified with a 1.5-inch front lift kit.

What is the benefit of the twin-tube design?
The twin-tube design is highly durable for street and work trucks; the outer tube acts as a shield, allowing the shock to continue functioning even if the outer body is dented by road debris.

Are boots included with these shocks?
Yes, this set includes Rancho’s signature red protective boots to shield the piston rods from dirt and moisture.
