Arnott RH-5276 Suspension Ride Height Sensor - Rear

Rear Ride Height Sensor for Ford, Lincoln, and Mercury

The Arnott RH-5276 is a rear suspension ride height sensor for select Ford Crown Victoria, Lincoln Town Car, and Mercury Grand Marquis models. It monitors suspension position and sends the signal needed to help the air suspension system maintain proper ride height.

Built as a new standard-grade replacement, this sensor uses a black housing and a single 3-pin rectangle female connector with blade terminals. It is engineered for durability and lab tested for up to one million cycles, with resistance to road debris, water, and salt exposure.

Detailed Description

Arnott RH-5276 is a rear suspension ride height sensor designed for vehicles with air suspension control. It reads suspension position and relays that information to the system so ride height can be monitored and corrected as needed. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Compatible with rear applications on the Ford Crown Victoria, Lincoln Town Car, and Mercury Grand Marquis, RH-5276 is a direct-fit service part for restoring proper sensor function on these platforms.

What This Part Helps Address

• Incorrect rear ride height readings
• Air suspension warning or control issues
• Uneven rear suspension stance
• Sensor failure from moisture or road contamination
• Intermittent suspension position signal loss

Installation Notes and Tips

Verify connector shape, terminal style, and rear-position fitment before installation. Mounting hardware is not included, so reuse or source the required hardware as needed. Inspect the linkage, wiring, and connector condition during replacement to help prevent repeat failures. For vehicles with similar wear patterns, replacing the sensor in pairs is recommended.

Quality Assurance

Arnott designs this sensor as a new replacement part and validates durability through lab testing for extended cycle life. The housing is built to resist common underbody exposure such as water, salt, and debris, supporting reliable operation in daily driving conditions.
