This high performance Regulator Rectifier will work on the 2004-2006 Rhino 450 and 660 Tthis brand new High Performance Regulator Rectifier will allow you will gain UP TO 7% more horsepower than stock Rhino Regulator Rectifier How does it work? There is an extra sensor and switch in the regulator rectifier. When the battery is near fully charged, the sensor instructs the switch to control the Magneto Rotor to run without cutting the magnet field. The rotor then runs lighter and saves the power to the engine. The engine gains more horsepower which allows your Rhino to drive faster.
