Frequently Asked Questions
Why choose MOSFET over stock?
Stock regulators use older shunt technology that dumps excess energy as heat. MOSFET regulators switch on/off rapidly, running significantly cooler and providing a more stable charging voltage.
Will this fit my 2003 Fat Boy?
Yes, this fits all Twin Cam 88 Softail models from 2001 to 2006, including the Fat Boy.
Do I need to modify the wiring?
No, this unit is designed with the correct stator plug and DC output leads to match the factory harness on these specific years.
Note: Please verify your OEM part number before ordering to ensure compatibility.
