Please Note: There were 2 different regulators used on 2017-2018 Polaris Sportsman 570 models. Please compare your original to our pictures. The other possible regulator is RMS021-107099.

When using this regulator on 2016-2018 Polaris Sportsman 570 models, please pay close attention to the stator and regulator wiring harness routing. The OEM wire routing was very poor, and allowed the harness to rub against the motor, damaging the insulation and damaging the charging system. We recommend routing your stator/regulator wiring outside of the frame rail, and securing the harness to the frame with zip ties. This should prevent any future damage to the wiring harness.

Battery condition is extremely important. No voltage regulator can work correctly with a bad or weak battery. Always fully charge your battery before performing any charging system tests or replacing parts. If there is any doubt, have the battery load tested or replaced.

Before installing your new 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.

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

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

*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.
