Rancho RS5000X 0″ Rear Lift Shocks for 1967-1972 GMC C3500 2WD

Part Number: RS55113

Summary: The Rancho RS5000X series leverages a patented progressive rebound and compression disc system to significantly improve the handling and ride quality of your GMC C3500. Designed for vehicles at stock ride height, these twin-tube gas pressurized shocks provide a consistent, smooth street feel while maintaining the durability required for heavy-duty work. The cross-tuned technology ensures that your classic truck remains stable and controlled under varying load conditions.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound discs provide a gradual transition during impact to ensure a smoother ride over harsh terrain.
• Nitro-Carburized Piston Rod: The heavy-duty 16mm rod construction provides increased structural rigidity and corrosion resistance to ensure a long service life in demanding environments.
• Gas Pressurized Twin-Tube Design: Low-pressure nitrogen charging reduces oil aeration and foaming to provide consistent damping performance during continuous cycling.
• Protective Shock Boot: The included polyvinyl accordion boot provides a physical barrier for the oil seal and piston rod to ensure protection against road debris and contaminants.
