Rancho RS5000X 0″ Front Lift Shocks for 1974-1983 Plymouth PB300, PB350

Part Number: RS55199

Summary: The Rancho RS5000X series leverages advanced CrossTun technology to provide a significant upgrade over factory damping for your Plymouth PB-Series van. Designed for stock height applications, these twin-tube gas-pressurized shocks utilize a unique valving system that minimizes aeration and foaming. This ensures consistent performance and a smooth, controlled ride during both daily commuting and light-duty hauling. The durable construction is engineered to withstand the rigors of aging suspension geometry while maintaining excellent street comfort.

Features

• CrossTun Technology: A specialized progressive valving system provides increased control at varying speeds to ensure a balanced ride across different road surfaces.
• Nitro-Carburized Piston Rod: The heavy-duty 16mm rod construction provides superior corrosion resistance and structural integrity to ensure long-term durability in harsh environments.
• Gas Pressurized Twin-Tube: The nitrogen gas charge provides reduced oil foaming and cavitation to ensure consistent damping force during repetitive cycling.
• Protective Boot: The included red polyvinyl accordion boot provides a physical barrier for the oil seal and piston rod to ensure protection against road debris and contaminants.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks are configured for a 0-inch lift and are designed to replace factory-length dampers without changing the vehicle’s ride height.

Is any modification required for installation?
Yes, according to the fitment notes, slight grinding of the lower control arm is required to ensure proper clearance and seating of the shock.

What is the benefit of the twin-tube gas design?
The twin-tube gas-pressurized design provides a larger oil capacity for cooling and uses nitrogen gas to prevent the oil from foaming, ensuring the shock maintains its damping effectiveness over long drives.
