Detailed Description

Arnott RH-5275 is a ride height sensor used in air suspension systems to report suspension position and support correct vehicle stance. It is engineered for the front left location on 2003-2006 Ford Expedition and 2004-2006 Lincoln Navigator models. The sensor uses a black housing and a single 3-pin rectangle female connector with blade terminals, matching the specified electrical interface for the application. This part cross-references OE-style numbers such as 3L1Z5359AB and 6L1Z5359C for the same application.

For buyers searching for a 2003-2006 Ford Expedition front left ride height sensor or a 2004-2006 Lincoln Navigator front left suspension level sensor, RH-5275 provides a direct replacement option. Arnott RH-5275 is also referenced by the part number RH-5275 for catalog and service lookup.

What It Helps Address

• Suspension height sensor fault codes
• Incorrect ride height readings from the air suspension system
• Uneven vehicle stance at the front left corner
• Air suspension response issues caused by a worn sensor
• Electrical connection problems at the sensor interface

Installation Notes and Tips

Verify the front left position and connector style before installation. Mounting hardware is not included, so reuse or source the required hardware separately as needed. Inspect the linkage, connector, and surrounding suspension components for wear or corrosion before installing the new sensor. Because the manufacturer recommends replacement in pairs, inspect the opposite side sensor during service on Expedition and Navigator air suspension systems.

Quality Assurance

Arnott tests this sensor for durability and cycle life, with lab validation up to one million cycles. The housing is built to resist common road contaminants such as water, salt, and debris, supporting long-term service in demanding suspension environments.
