Rancho RS5000X 2.5-4″ Lift Shocks for 1987-1991 GMC V3500 4WD

Part Number: RS55001 / RS55134

Summary: The Rancho RS5000X series leverages a patented progressive rebound and compression disc system to enhance the handling of your lifted GMC V3500. Designed specifically for vehicles with a 2.5 to 4-inch lift, these shocks utilize a twin-tube gas pressurized design to provide exceptional durability and dent resistance during off-road use. By minimizing aeration and foaming, the RS5000X ensures consistent damping performance and a smooth, controlled street ride for your classic 4WD square-body.

Features

• Cross-Tuned Technology: A unique progressive valving system provides increased control at higher speeds while maintaining comfort at lower speeds to ensure a balanced ride across all terrains.
• Twin-Tube Gas Pressure: The nitrogen-charged 5/8-inch piston rod design provides consistent damping and reduces shock fade to ensure reliable performance during heavy-duty hauling or trail use.
• Protective Boot: Included red polyvinyl accordion boots provide a physical barrier for the piston rod and oil seal to ensure longevity against debris and corrosion.
