The Rhino 660 charging system is a secondary charging system in addition to the stock charging system. When this kit is installed you will have the ability to run 500 watts of power. The kit comes complete with a alternator, alternator bracket, billet aluminum pulley, belt, tie rod assembly (for adjusting belt tension), relay, wiring and hardware. We have also included detailed installation instructions and a wiring diagram to ensure proper installation of the kit. This kit is the only way to get more electrical power out of your Rhino beyond our HO stator kit.
