This Arnott ride height sensor (part code RH-4272) is designed to accurately monitor and report the vehicle's suspension height to the control module. Proper functioning of this sensor is crucial for maintaining the correct ride height, which directly impacts vehicle handling, comfort, and load-carrying capacity. When the suspension height changes due to load variations or driving conditions, this sensor sends a signal to the vehicle's air suspension system. The system then adjusts the air springs to bring the vehicle back to its pre-set level. This ensures a consistent and comfortable ride, regardless of the load or road surface. Arnott is known for its quality suspension components, and this sensor is built to meet or exceed OEM specifications. Replacing a faulty ride height sensor can resolve issues such as uneven suspension, warning lights on the dashboard, or improper leveling of the vehicle.
