Rancho RS5000X 5-6″ Rear Lift Shocks for 2005-2016 Ford F-250 4WD

Part Number: RS55045

Summary: The Rancho RS5000X series utilizes a sophisticated twin-tube gas pressurized design to provide exceptional durability and ride quality for lifted Super Duty trucks. Engineered specifically for vehicles with 5 to 6 inches of rear lift, these shocks feature a unique Cross-Tuned valve system that balances on-road comfort with off-road control. The robust shock body is designed to resist dents from trail debris while maintaining a smooth, consistent damping profile for daily driving and heavy-duty use.

Features

• Cross-Tuned Technology: A progressive engagement valving system provides a smooth ride during initial travel to ensure comfort during highway cruising.
• Twin-Tube Gas Pressure: The 2.25-inch diameter reserve tube provides increased fluid capacity to ensure cooler operating temperatures during heavy work cycles.
• Nitro-Carburized Piston Rod: A heavy-duty hardened rod construction provides superior corrosion resistance to ensure long-term seal integrity in harsh environments.
• Protective Boot: The included high-quality accordion boot provides a physical barrier against mud and grit to ensure the longevity of the internal seals.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically lengthened and valved to accommodate Ford trucks already equipped with a 5 to 6-inch rear lift kit.

What is the benefit of the RS5000X twin-tube design?
The twin-tube design allows for a larger outer body that acts as a reservoir for oil, keeping the internal valving cooler and protecting the inner pressure tube from rock dents.

Are these compatible with Dually trucks?
These specific units are designed for Single Rear Wheel (SRW) configurations and are not recommended for Chassis Cab or Dually models.
