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.

With
design
This product is an advanced design that lowers operating temperatures for extended longevity and better performance than the OEM part.
Brand new Mosfet Voltage Regulator Rectifier
STOP BURNING YOUR 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.

Our RM30801H is an improved MOSFET voltage regulator with a much larger housing than the original YFZ450R regulator. It will not fit in the original mounting location. It will plug in to the stock connector with the attached wiring harness, but will require you find a new mounting location on your vehicle.
