Rancho RS5000X 0″ Rear Lift Shocks for 1941-1963 Jeep MB, M38 4WD

Part Number: RS55119

Summary: The Rancho RS5000X series redefines classic twin-tube performance for your vintage Jeep or utility vehicle. Engineered with a unique Progressive Engagement Valving system, these rear shocks provide a smooth, comfortable street ride while maintaining the durability required for light off-road use. By utilizing a larger shock body, the RS5000X increases oil capacity to manage heat more effectively than standard replacement shocks, ensuring consistent damping performance throughout your drive.

Features

• Progressive Engagement Valving: A custom-tuned internal shim stack provides increased control during high-velocity impacts to ensure a smooth transition between street comfort and off-road stability.
• 2.25-inch Body Diameter: An oversized shock body provides increased fluid capacity to reduce internal temperatures and ensure fade-free performance during extended use.
• Nitrogen Gas Pressurized: A 150 PSI gas charge minimizes air-to-oil mixture (aeration) to ensure immediate damping response and consistent control.
• Protective Boot Included: A durable red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against dust and debris.

Frequently Asked Questions

Will these shocks lift my Jeep?
No, these shocks are designed for vehicles at factory ride height (0″ of lift) and do not provide any lift height on their own.

Is the boot required for installation?
While the shocks can function without them, the included boots are highly recommended to protect the piston rod from pitting and premature seal failure.

What is the benefit of the RS5000X over the original RS5000?
The RS5000X features improved valving that engages more progressively, offering a significant upgrade in ride quality on pavement without sacrificing off-road durability.
