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

Part Number: RS55001 / RS55227

Summary: The Rancho RS5000X series utilizes a cross-tuned twin-tube design to provide a significant upgrade in ride quality for lifted Chevy K3500 and GMC Yukon applications. Engineered to handle the increased demands of a 4-inch lift, these shocks feature a unique valving system that minimizes harshness over small bumps while maintaining control during heavy-duty use. This kit offers a balanced solution for drivers seeking durable, gas-pressurized performance for both daily commuting and off-road excursions.

Features

• Progressive Engagement Valving: A custom-tuned compression disk stack provides reduced initial impact harshness to ensure a smoother ride on paved surfaces.
• Gas Pressurization: High-pressure nitrogen gas charge provides consistent damping force to ensure zero aeration and reduced fade during spirited driving.
• Enlarged Shock Body: A 2.25-inch reserve tube provides increased oil capacity to ensure lower operating temperatures during heavy hauling or towing.
• Nitro-Carburized Piston Rod: Heavy-duty construction provides superior corrosion resistance to ensure long-term durability in harsh environments.
