Rancho RS5000X 0″ Lift Shocks for 2017-2025 Ford F-350 4WD

Part Number: RS55042

Summary: The Rancho RS5000X Series utilizes advanced CrossTech Progressive Engagement Valving to significantly improve the handling and ride quality of your Ford F-350. Designed for vehicles at stock ride height, these shocks feature a large 2.25-inch reserve tube that increases oil capacity for cooler operation during heavy-duty use. This twin-tube gas pressurized design is engineered to reduce aeration and provide a smooth, controlled feel whether you are commuting or hauling heavy loads.

Features

• Progressive Engagement Valving: A custom-tuned internal shim stack provides a gradual transition of damping force to ensure a smooth ride over small bumps while maintaining control during large impacts.
• Gas Pressurization: Low-pressure Nitrogen gas charge provides a consistent oil-to-gas interface to ensure reduced aeration and fade during spirited driving.
• Large Reserve Tube: The 2.25-inch twin-tube body provides increased fluid capacity to ensure lower operating temperatures and consistent performance under load.
• Nitro-Carburized Piston Rod: A heavy-duty 16mm rod construction provides superior scuff and corrosion resistance to ensure long-term seal integrity.

Frequently Asked Questions

Do these shocks provide any lift to my truck?
No, these shocks are configured for a 0-inch lift and are designed to replace the factory-length dampers without changing the ride height.

Is this a complete set for the front and rear?
Yes, this specific SKU includes a full set of four shocks (two front and two rear) for a complete suspension refresh.

How does the RS5000X differ from a standard shock?
The RS5000X features CrossTech valving and a larger body diameter than most OE units, which leads to better heat dissipation and a more refined damping curve.
