AISIN HST-029 OEM Ride Height Sensor - Compatible with Select Lexus GX470; Toyota 4Runner

Product Description AISIN Ride Height Sensors are engineered to exact OE specifications to ensure proper function of vehicle air suspensions and HID headlight leveling systems. Ride height sensors are a critical component used in an air suspension system to signal a control unit when the vehicle is riding low or high. In response to this signal, compressed air is either sent to or vented from the air springs. Some vehicles, most often those with HID headlights, have an automatic headlight leveling system. This system automatically keeps the headlights adjusted for optimal road illumination and to prevent glare that could blind the drivers of oncoming vehicles. Sensors detect changes in vehi​cle attitude caused by passenger or cargo weight and vehicle accelera​tion or braking. These signals are sent to an electronic control unit that in turn commands electric mo​tors to adjust the headlight angle. With superior OE technology and know-how, AISIN ensures that every ride height sensor provides perfect OE form, fit, and function and installs easily. AISIN ride height sensors include the sensor, mounting bracket, and linkage arm (adjustable or non-adjustable depending on application). Set Contains: Sensor
