Product Description

This is our CNC’d magnet rotor that fits original Fairbanks housings as well as our billet housings. The advantage of the Joe Hunt magnet rotor is that it utilizes neodymium magnets that never loose their charge, so you’ll never have to worry that your magneto isn’t operating at its optimum performance level. Another advantage of the neodymium magnets is that the output amperage is increased over a stock rotor, so you not only get the piece of mind that you mag is performing at it’s best, but you also get a hotter spark at the plug.

This unit replaces the stock Fairbanks one piece magnet rotor and drive shaft assembly. Includes the correct tach drive splines machined on the drive shaft to allow the use of the stock Harley mechanical tach drive.
