Rancho RS5000X 0″ Rear Lift Shocks for 1985-2005 Chevy Van Astro Mini 2WD

Part Number: RS55147

Summary: The Rancho RS5000X series utilizes an innovative cross-tuned twin-tube design to enhance the ride quality of your Chevy Astro or GMC Safari. Engineered with a unique progressive engagement valving system, these shocks provide a smooth, comfortable street ride while maintaining the durability needed for heavy-duty hauling or high-mileage van applications. By minimizing fluid aeration and cavitation, the RS5000X ensures consistent damping performance across varying road conditions and temperatures.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound discs provide a smooth transition between damping stages to ensure refined ride quality and reduced body roll.
• Gas Pressurization: High-pressure nitrogen gas charge provides a consistent oil-to-gas interface to ensure zero aeration and fade-free performance during extended highway travel.
• Twin-Tube Construction: A 2.25-inch diameter reserve tube provides increased fluid capacity and dent resistance to ensure long-term durability in commercial or passenger environments.
• Nitro-Carburized Piston Rod: Heavy-duty 16mm rod construction provides superior scuff resistance and corrosion protection to ensure a long seal life.
