Summary: The Rancho RS5000X series leverages advanced CrossTune technology to provide a significant upgrade over factory dampening for your GMC C1500. Designed as a high-performance twin-tube gas-pressurized shock, it features a unique valving system that minimizes aeration and foaming. This configuration ensures consistent performance and smooth street comfort, making it an ideal solution for classic truck owners seeking modern ride quality and long-term durability.

Features

• CrossTune Technology: A progressive engagement valving system provides a custom-tuned ride for both on-road comfort and off-road stability to ensure predictable handling in various driving conditions.
• Twin-Tube Design: A 2.25-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures and better dent resistance during rugged use.
• Nitrogen Gas Pressure: High-pressure gas charging provides a reduction in fluid foaming and aeration to ensure consistent damping force throughout the shock’s travel.
• Nitro-Carburized Piston Rod: A heavy-duty 16mm rod construction provides superior corrosion resistance and structural integrity to ensure a long service life.

Frequently Asked Questions

Will these shocks lift my GMC C1500?
No, these shocks are configured for a 0-inch lift height and are designed to replace factory-length shocks without changing the vehicle’s ride height.

What is the benefit of the RS5000X gas pressure?
The nitrogen gas charge keeps the internal shock fluid under pressure, which prevents bubbles from forming (aeration). This ensures the shock maintains its damping effectiveness even on washboard roads.

Are boots included with these shocks?
Yes, Rancho RS5000X shocks include protective red dust boots to shield the piston rod and oil seal from road debris and contaminants.
