MOSFET Regulator Rectifier – Polaris Sportsman 500 / 800 / Ranger 5...
An advanced MOSFET-type replacement regulator rectifier for a range of Polaris Sportsman, Ranger, and RZR models produced between 2010 and 2015. Unlike conventional diode-style regulators, this MOSFET design runs significantly cooler and features built-in overheat protection - temporarily shutting off to cool down rather than burning out. The unit regulates AC output from the stator and converts it to controlled DC voltage to maintain correct battery charge and protect electrical components from voltage overload.
Manufactured to exceed OEM specification using higher-grade electrical components and an improved heat sink. Cross-references Polaris OEM part number 4012748 for straightforward identification. Verify your model and year against the fitment table before ordering.
