I have been custom building alternators for over 18 years and have a very good reputation throughout the world. I install custom overdrive pulleys and resistors to help the unit to "cut on" at a lower rpm than other high output alternators. I also use a specially designed rear housing to keep the alternator cooler on specific units.

We also offer special mods for high rpm applications to keep your alternator reliable under extreme use. We also offer in house powdercoating and painting.
