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

Part Number: RS55227

Summary: The Rancho RS5000X series utilizes a cross-tuned twin-tube design to provide a significant upgrade in ride quality for lifted GMC K3500 applications. Engineered to handle the increased demands of a 4-inch rear lift, these shocks feature a unique valving system that minimizes harshness over road imperfections while maintaining firm control. The durable construction ensures consistent performance under heavy loads, making them an ideal solution for drivers seeking a balance between daily street comfort and dependable off-road durability.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smooth transition between damping forces to ensure a comfortable ride during normal driving and firm control during aggressive maneuvers.
• Twin-Tube Gas Pressure Design: The 2.25-inch diameter shock body provides increased fluid capacity to ensure cooler operating temperatures and reduced fade during heavy-duty use.
• Nitro-Carburized Piston Rod: A heavy-duty 16mm rod construction provides superior corrosion resistance and structural integrity to ensure long-term seal protection.
• Polyurethane Bushings: High-density mounting points provide enhanced durability and reduced deflection to ensure precise suspension feedback.
