Rancho RS5000X 2.5″ Rear Lift Shocks for 2005-2016 Ford F-350 4WD Single Rear Wheel

Part Number: RS55047

Summary: The Rancho RS5000X series utilizes an innovative cross-tuned twin-tube design to significantly improve the ride quality of your Ford F-350. Engineered specifically for vehicles with a 2.5-inch rear lift, these shocks feature a unique progressive engagement valving system that minimizes harshness during initial impacts. This setup provides the ideal balance of rugged off-road durability and smooth street comfort for heavy-duty applications.

Features

• Progressive Engagement Valving: A custom-tuned internal shim stack provides restricted oil flow during initial compression to ensure a smooth ride over small road imperfections.
• Gas Pressurization: High-pressure nitrogen gas charge provides a consistent oil-to-gas barrier to ensure reduced aeration and shock fade during heavy hauling.
• Twin-Tube Body: A 2.25-inch reserve tube provides increased oil capacity and dent resistance to ensure long-term reliability in harsh environments.
• 16mm Nitro-Carburized Rod: The heavy-duty piston rod provides superior structural rigidity and corrosion resistance to ensure a long service life.

Frequently Asked Questions

Will these shocks lift my Ford F-350?
No, these shocks do not create lift. They are specifically valved and length-tuned to work with a truck that already has a 2.5-inch rear lift kit installed.

Do these shocks come with the red boots?
Yes, these RS5000X shocks include Rancho’s signature red protective boots to keep debris away from the piston rod and oil seal.

What is the benefit of the twin-tube design on an F-350?
The twin-tube design is highly durable for work trucks; if the outer body is dented by a rock or debris, the inner cylinder remains functional, allowing the shock to continue operating.
