Rancho RS5000X 4″ Lift Shocks for 1988-2000 GMC K3500 4WD

Part Number: RS55001

Summary: The Rancho RS5000X series features an innovative cross-tuned twin-tube design that provides a significant upgrade over factory damping for your GMC K3500. Engineered for vehicles with a 4-inch lift, these shocks utilize a unique valving system that minimizes aeration and shock fade during demanding use. This setup ensures a smooth, controlled ride on the street while maintaining the rugged durability required for off-road excursions.

Features

• Progressive Engagement Valving: A custom-tuned compression disk provides a soft ride during initial travel to ensure comfort on highway surfaces.
• Gas Pressurization: 150 PSI nitrogen gas charge provides reduced oil foaming and aeration to ensure consistent damping performance in harsh environments.
• Large Shock Body: A 2.25-inch reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy-duty cycles.
• Heavy-Duty Rod: A 16mm nitro-carburized piston rod provides superior scuff resistance and structural integrity to ensure long-term seal life.
