If you like traditional looks and reliable, modern performance, you’ll love this cool "shorty" alternator. It has the look of an original generator, but is really a 6-volt, negative-ground alternator that produces 50 amps at idle and 55 amps going down the road. This model is designed to fit 1948-54 GM applications and features a simple one-wire hookup.
We offer this one wire alternator in a black powder coat finish with included stock-appearing mounting brackets (the stock fan carrier bolts to that bracket) and pulleys that accept wide 3/8” belts.
- Easy one-wire hookup
- GM short frame (5.95 field housing)
- 6 volt negative ground
- 50 amp idle, 55 amp cruise, 60 amp top end
- 3/8" wide belt pulley included
- Some applications may require pulley transfer from original generator
- Uses stock-appearing bracket and fan carrier bolts
