MOSFET Series Regulator

Fits Harley Davidson Softail & Fat Boy (2001-2006)

Upgrade your Harley's charging system with this state-of-the-art **MOSFET Voltage Regulator Rectifier**. Designed to replace the standard shunt-style regulator on **2001-2006 Softail** models (including Fat Boy and Heritage), this unit runs significantly cooler and provides a more stable voltage output.

The advanced **MOSFET technology** reduces heat build-up, protecting your stator and battery from thermal stress. This kit is a direct plug-and-play solution featuring the correct connectors for a hassle-free installation.

COOLER OPERATION: MOSFET regulators waste less energy as heat, extending the life of your entire charging system compared to OEM units.

Key Features

  • MOSFET Tech: High efficiency, low heat.
  • Direct Fit: OEM connectors pre-installed.
  • Heavy Duty: Rated for 50 Amps.
  • Precise Voltage: Stable 14.5V output.

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.
