Keep your air suspension reading the road accurately with the Arnott Industries Suspension Ride Height Sensor RH-3777. It is a direct-fit replacement for the rear left position on the 2010-2023 Lexus GX460 (All engines), with one sensor used per application. This part is listed under two names: suspension ride height sensor and headlight level sensor.
Precision ride height sensing: Arnott's OES ride height sensor is designed for accurate suspension calibration. It measures the changing distance between the road and the vehicle's chassis.
Works with the air suspension: The sensor sends its reading to the Electronic Control Unit (ECU). The ECU then signals the air suspension compressor to add or release air in the air struts as needed.
Built to replace a worn or damaged sensor: Ride height sensors can wear out. They are also exposed to road debris, accidents, and water and salt intrusion. Replacing a failed sensor helps protect the rest of the air suspension system from further damage.
Replace in pairs: For best results, Arnott recommends replacing ride height sensors in pairs.
Signs this sensor may need replacing include uneven ride height at one corner, an air suspension warning, or a compressor that runs more than usual. Other components can cause the same symptoms, so diagnose the system before replacing parts. If a failed rear left ride height sensor is the cause, the RH-3777 is designed to let the vehicle respond to road conditions again.
Specifications: Black, triangle-shaped male connector with 3 male blade terminals. Standard replacement grade. Mounts at the rear left. Quantity per application: 1. Country of origin: Japan.
