The Rancho RS5000 X shocks feature Cross Tuned technology, which includes an exclusive rebound valving system and advanced compression phase. This technology improves overall handling and performance both on and off the road. The Exclusive Progressive Engagement Valving is custom-tuned for each vehicle, helping to reduce initial impacts at low speeds and minimize a rough ride.

Constructed with durability in mind, these shocks feature a 16mm nitro-carburized piston rod to reduce scuffs and corrosion, double-welded loops at stress areas, and a 35mm sintered iron piston for enhanced structural integrity. A polyvinyl protective boot further enhances the shocks' strength and resilience.

The large twin-tube body, filled with all-weather fluid, allows for cooler operation, increased vehicle control, and the ability to withstand internal temperatures ranging from -40 to 248°F. This ensures smooth performance, even in extreme temperature conditions.

Polyurethane rebound bumpers and rubber bushings help absorb ride harshness, while the fluon-banded piston enhances responsiveness to changing road conditions, resulting in an overall smoother ride. The nitrogen gas pressurization of 150 PSI helps minimize air-to-oil mixture, reducing damping performance fade and foaming.

The Compression Control Valve is custom-tuned for each vehicle to regulate fluid transfer, absorbing impacts without disc flutter and maintaining shock motion control. The low-friction, self-lubricating seal retains gas and oil for quicker rebound and smoother compression, while the application-specific piston delivers heightened control of shock motion due to the expanded piston area.

In summary, the Rancho RS5000 X shocks are designed to provide improved handling, performance, and durability for a wide range of Ford Super Duty trucks. With their exclusive features and advanced technology, these shocks are built to deliver a smooth, controlled, and reliable ride, both on and off the road.
