Rancho RS5000X 0″ Lift Shocks for 2005-2006 Ford F-450 Super Duty

Part Number: RS55042

Summary: The Rancho RS5000X series provides a significant upgrade over factory dampening for the Ford F-450 and F-550 Super Duty. Utilizing a sophisticated gas-pressurized twin-tube design, these shocks are engineered to provide smooth street comfort while maintaining the rugged durability required for heavy-duty work cycles. By minimizing aeration and foaming, the RS5000X ensures consistent performance whether the truck is empty or under a heavy payload.

Features

• Cross-Tuned Technology: A unique progressive rebound and compression disc system provides custom-tuned valving to ensure optimal control and comfort on both highway and gravel surfaces.
• Twin-Tube Body: A 2.25-inch diameter reserve tube provides increased fluid capacity to ensure cooler operation and consistent dampening during heavy hauling.
• Nitro-Carburized Piston Rod: The heavy-duty 16mm rod construction provides superior scuff resistance and corrosion protection to ensure a long service life in harsh environments.
• Gas Pressurization: High-pressure nitrogen gas charge provides a reduction in oil foaming and cavitation to ensure immediate response to road irregularities.

Frequently Asked Questions

Will these shocks lift my Ford F-450?
No, these shocks are configured for 0-inch lift heights and are designed to replace the factory-length dampers without changing the vehicle’s stance.

What is the benefit of the twin-tube design on a Super Duty?
The twin-tube design is exceptionally durable; the outer tube acts as a shield, meaning if the body is dented by road debris, the internal piston remains functional and unaffected.

Are the shock boots required for installation?
While the shocks can function without them, the included red boots protect the nitro-carburized rod from rock chips and salt, extending the life of the seals.
