A direct-fit replacement regulator rectifier for the Honda TRX 300 EX Fourtrax and TRX 300 EX Sportrax produced between 1993 and 2006. 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 for enhanced charging performance, with every unit tested before dispatch. Cross-references Honda OEM part numbers 31600-HM3-003, 31600-HM3-900, and 31600-HM3-901 for straightforward identification. Verify your model and year against the fitment table before ordering.
