ESR845 Regulator/Rectifier Polaris Ranger/RZR

ESR845 is a high quality regulator/rectifier that replaces the OEM regulator on various models.

Our ESR845 offers superior performance in the same plug-in package as the OEM unit. We utilize our newest power circuit design and combine it with a highly efficient heat sink. The connector is identical to OEM so it plugs right in.

ESR845 offers a more stable battery voltage, a perfect charge rate for the battery and a cooler running unit which vastly improves reliability.

This is a great upgrade for the stock unit. ESR845 is supplied with a full one year warranty.
