Improved Mosfet Regulator Rectifier Perfomance Upgrade for Polaris RZR XP & Ranger 900 / 900 Turbo 2013-2016

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 3/16/12 and after. For the version built 3/15/12 and before, the right regulator is part RM30351. 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.

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

Don't settle for an unreliable charging system!

2013-2016 RZR 900/1000 models are well known for repeated voltage regulator failures due to manufacturing quality issues and poor placement on the vehicle.

Fix and forget the problem with RMS Lab's advanced technologies!

With increased demand for an alternative solution to subpar OEM parts and unproven manufacturer recalls, we had our RMS Labs’ engineers tackle the problem. They came up with a permanent solution to give Polaris RZR owners confidence in their vehicles once and for all.

This Kit Includes:

  • OEM regulator housing for direct replacement
  • RMSTATOR Renowned MOSFET regulation circuit for low operating temperature

RMS Labs technologies included

RMSTATOR renowned MOSFET voltage regulation design
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 wiring harness with OEM-quality heavy-duty connectors
Made with the same Delphi connectors as OEM Polaris parts, our wiring harnesses are manufactured in a factory with controlled quality processes. They use the same Cross-Link braided copper wire as the OEM parts, and resist heat, oil, acid, gas and more with very low electrical resistance.

Plug & Ride design
Our voltage regulator housings are manufactured to OEM specifications for a fast and easy installation.

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