Detailed Description

Arnott RH-5274 is engineered for the front right position on 2003-2006 Ford Expedition U222 and 2004-2006 Lincoln Navigator U228 models. This ride height sensor measures suspension position and communicates with the air suspension system so the vehicle can maintain proper ride height during normal driving conditions. The compact black housing and 3-pin rectangle connector support a direct-style electrical connection for the listed applications. Arnott RH-5274 is a practical replacement choice when the original sensor is worn, damaged, or no longer reporting suspension position accurately. This part cross-references Ford OE numbers 3L1Z5359AA and 6L1Z5359CC for the same application.

What It Helps Fix

• Suspension height readings that are no longer accurate
• Air suspension warning lights related to ride height sensing
• Uneven vehicle stance at the front right corner
• Delayed or incorrect air suspension response
• Sensor failure caused by exposure to debris, water, or road salt

Installation Notes and Tips

Verify the connector shape, terminal style, and front right location before installation. Mounting hardware is not included, so reuse serviceable existing hardware or source the correct fasteners separately. Inspect the surrounding suspension components and wiring for wear or corrosion before replacing the sensor. Arnott recommends replacing ride height sensors in pairs when service is needed on the same axle or corner set.

Quality Assurance

Arnott tests this sensor for durability and long service life, including up to one million operating cycles. The design is intended to withstand common underbody exposure while maintaining consistent suspension position feedback for the air suspension system.
