Rancho RS5000X 2.5-4″ Front Lift Shocks for 1969-1986 Chevy K-20 4WD

Part Number: RS55001

Summary: The Rancho RS5000X series leverages a patented progressive engagement valving system to significantly improve the handling and ride quality of your lifted Chevy K-20. Designed for vehicles with 2.5 to 4 inches of front lift, these gas-pressurized twin-tube shocks provide exceptional durability and dent resistance for off-road environments. By minimizing aeration and shock fade, the RS5000X ensures a smooth, controlled street ride while maintaining the ruggedness required for heavy-duty 4WD applications.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a gradual transition between low and high-speed damping to ensure a comfortable ride over varied terrain.
• Gas Pressurization: A high-pressure nitrogen charge provides a consistent oil-to-gas interface to ensure reduced aeration and more responsive damping.
• Twin-Tube Body: A 2.25-inch reserve tube provides increased oil capacity and physical protection for the inner pressure tube to ensure long-term durability in harsh off-road conditions.
• Nitro-Carburized Piston Rod: The heavy-duty 16mm rod provides superior scuff and corrosion resistance to ensure maximum seal life and structural integrity.
