Rancho RS5000X 0″ Rear Lift Shocks for 1973-1986 GMC C3500 2WD

Part Number: RS55118

Summary: The Rancho RS5000X series utilizes a patented progressive engagement valving system to significantly improve the handling and ride quality of your GMC C3500. Designed for vehicles at stock ride height, these gas-pressurized twin-tube shocks excel at absorbing harsh road impacts while maintaining consistent performance during work or daily transit. The durable construction and large shock body provide increased fluid capacity, ensuring these shocks remain cool and effective under heavy loads.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition to firm control to ensure a smooth street ride without sacrificing stability.
• Gas Pressurization: High-pressure nitrogen gas charge provides a reduction in aeration and foaming to ensure consistent damping performance during rapid cycling.
• Twin-Tube Design: A 2.25-inch diameter outer tube provides extra oil capacity and dent resistance to ensure long-term durability in rugged environments.
• Protective Boot: Included polyvinyl accordion boot provides a physical barrier for the piston rod to ensure seal longevity against road debris and salt.
