Rancho RS5000X 0″ Rear Lift Shocks for 1961-1965 Dodge WM300 4WD

Part Number: RS55119

Summary: The Rancho RS5000X series utilizes a cross-tuned twin-tube gas pressure design to provide a significant upgrade over factory damping for your Dodge WM300. Engineered with a unique progressive engagement valving system, these shocks provide smooth street comfort while maintaining firm control during off-road or utility use. The robust twin-tube body is specifically designed for durability and dent resistance, ensuring reliable performance in demanding environments. These shocks are configured for vehicles at stock ride height (0″ lift) to maintain original geometry while improving overall ride quality.

Features

• Progressive Engagement Valving: Custom-tuned internal valving provides a soft ride during initial travel to ensure comfort on washboard roads and city streets.
• Gas Pressurized Twin-Tube Design: A 150-PSI nitrogen gas charge provides reduced aeration and foaming to ensure consistent damping performance under load.
• Heavy-Duty Construction: A 2.25-inch diameter shock body provides increased fluid capacity to ensure cooler operating temperatures during extended use.
• Nitro-Carburized Piston Rod: The hardened 16mm rod provides superior scuff resistance and corrosion protection to ensure long-term seal integrity.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks are designed to work with vehicles at the factory ride height (0″ lift) and do not provide any lift on their own.

What is the benefit of the twin-tube design for my Dodge WM300?
The twin-tube design is highly durable; if the outer tube is dented by debris, the inner working tube remains unaffected, ensuring you aren’t stranded on the trail.

Do these shocks include the protective boots?
Yes, these shocks come standard with Rancho’s signature red protective dust boots to keep the piston rod clean and protected from the elements.
