Rancho RS5000X 0″ Lift Shocks for 1970-1991 GMC G-3500

Part Number: RS55120

Summary: The Rancho RS5000X series utilizes an innovative cross-tuned twin-tube design to provide a significant upgrade over factory ride quality for your GMC G-3500. By incorporating a unique progressive engagement valving system, these shocks effectively manage impacts and road vibrations without sacrificing the durability required for heavy-duty applications. This set is specifically configured for vehicles at stock ride height (0″ lift), ensuring a perfect fit and restored handling characteristics.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smoother transition during initial impacts to ensure consistent comfort on varied road surfaces.
• Twin-Tube Gas Pressurized Design: A 2.25-inch diameter shock body provides increased fluid capacity to ensure cooler operating temperatures and reduced fade during extended use.
• Nitrogen Gas Charge: Pressurized gas displacement provides immediate response to road irregularities to ensure maximum tire-to-road contact.
• Protective Boot Included: A heavy-duty red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against debris.
