Before installing your new Mosfet Voltage Regulator Rectifier :

  • Check the AC output of the stator
  • Replace any burned or corroded connectors on stator and regulator rectifier
  • Check and repair any melted wiring
  • Use hi-temp dielectric grease on all connectors

Brand new Mosfet Voltage Regulator Rectifier

It is time to update or replace your voltage regulator with the advanced MOSFET type.

It runs cooler than all OEM diode style regulators. In addition, this rectifier has overheat protection, rather than burn up it will simply turn off for a while and cool off.

Key features

IMPROVED & HEAVY DUTY: OEM and most SCR type voltage regulator are known to fail more than often for these vehicles. Our RMS Labs took a best selling voltage regulator and made it tougher by using highly reliable components to regulate the voltage. The result : More than 83% less failures than a standard OEM-type voltage regulator.

RMSTATOR RENOWNED MOSFET COMPONENTS: Significantly decreases internal operating temperature with highly efficient MOSFET transistor regulation circuit. This technology runs much cooler than the OEM silicon rectifier regulation circuit and requires much less power to operate.

AUTOMOTIVE GRADE HEAVY-DUTY CONNECTORS: Increase contact surface for distributed voltage charge on pins & less heat generated at connectors levels

  • Direct replacement to your original unit
  • Plug-and-play, direct fit, easy installation
  • The quality exceeds the OEM equipment
  • Higher grade of electric components
  • All shipped products are tested

We have even included the opposite connector (main harness side) as we know these are often melted / corroded / defective and a major cause for repetitive electrical issues.

*All item pictures are accurate, if in doubt, do not hesitate and compare our item to your original part.

Why use Mosfet Enhanced technology?

Runs cooler

Runs much cooler than the traditional Shunt voltage regulator rectifier.

Saves gas

Less load on the stator, less work, less fuel is used and you save.

Regulated energy

The power charging your battery is steadier and smooth.


Extended battery life

Extends the battery’s life and cold cranking capacity.

More engine power

Removes stator load resulting in more engine power.

Optimized power

Optimize power delivery by switching the stator coils on or off.
