Rancho RS5000X 4″ Lift Shocks for 1988-2000 GMC C2500 2WD

Part Number: RS55128

Summary: The Rancho RS5000X series leverages a cross-tuned twin-tube design to deliver a significant upgrade in ride quality and durability for your lifted GMC C2500. Engineered with a unique valving system, these shocks mitigate harsh impacts while maintaining excellent control during highway transit or light off-road use. This complete set is specifically configured for vehicles with a 4-inch lift, ensuring the piston operates within its optimal stroke range for maximum longevity and comfort.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smooth transition between low and high-speed damping to ensure consistent comfort on varying road surfaces.
• Gas Pressurized Twin-Tube: Nitrogen gas charging reduces aeration and foaming provides rapid response times to ensure fade-free performance during extended use.
• 16mm Nitro-Carburized Rod: The heavy-duty hardened piston rod provides superior scuff resistance and structural integrity to ensure long-term durability in harsh environments.
• Protective Boot Included: A high-quality polyvinyl accordion boot provides a physical barrier against debris and mud to ensure the oil seals remain free from contaminants.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically sized and valved to accommodate a GMC C2500 that already has a 4-inch suspension lift installed.

What is the benefit of the RS5000X twin-tube design?
The twin-tube design is highly durable; if the outer body is dented by a rock or debris, the inner working tube remains unaffected, allowing the shock to continue functioning properly.

Are boots included with this set?
Yes, this kit includes red protective boots to safeguard the piston rods from road salt, dirt, and debris.
