A kit consisting of our drop-in replacement high power ESL770 stator, a regulator/rectifier and the wiring harness with connectors. You will have 150W of power on-tap enabling you to run multiple HID headlights if you would like to! Massive power that comes with a full one year warranty! NOTE: This is a 150watt output unit and as such has a much larger than OEM reg/rec unit. It may require relocating or minor modification to fit on some applications
