Arnott RH-3770 Suspension Ride Height Sensor - Rear

Arnott RH-3770 Ride Height Sensor

Arnott RH-3770 is a vehicle-specific suspension ride height sensor for the rear of select Lexus LX470 and Toyota Land Cruiser applications. It sends the height signal to the vehicle computer to help maintain correct suspension or headlight height, using a black female connector with a 3-terminal blade layout.

Built as a new OE-style replacement, this Arnott RH-3770 ride height sensor addresses worn or damaged factory sensors on the Lexus LX470 and Toyota Land Cruiser. It includes the sensor and linkage arm for rear suspension height feedback on the 1998-2007 Lexus LX470 and 2006-2007 Toyota Land Cruiser.
