65A Heavy Duty MOSFET Voltage Regulator Rectifier for Polaris RZR 900 XP / RZR XP 4 900 2011 2012 | OEM Repl.# 4013231

CAD$ 174.00
Availability: In stock
There are two possible regulators for the RZR 900 XP and RZR 4 900 XP 2012 models. This regulator fits models built 3/15/12 and before. For the version built 3/16/12 and after, the right regulator is part RM30313. Always check in the 'Fits models' section and please compare to your original part before buying.

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.

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
  • 65 ampere, for a long lasting regulator
  • 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.
