6 Volt GM Negative Ground

Get that nostalgic look of a generator and the reliable charging power of an alternator all in one! These alternators are designed to fit where the original generator was mounted.

If you want the look of an original generator, but the reliability and power of a modern alternator, the PowerGen from Powermaster is the answer. The PowerGen looks just like the generator your classic car came with or it can add the traditional look to any hot rod or street rod. But this is not old technology; it's a modern, powerful alternator that can keep up with all of the latest electrical accessories you have added to your ride. PowerGEN's offer one-wire operation, producing 75 amps, with a whopping 60 amps at idle and is only 1/4'' larger in diameter than a stock generator. They have a black finish just like the original generator.

Comes with pulley for 3/8 inch belt. Other pulleys options are available upon request.

The Short GM unit is 5.95 inches between the mounting ears and the Long GM is 7.13 inches between the mounting ears. For vehicles that have the P/S units driven off the rear of the OE generator, you would have to install a separate P/S pump.
