Description
GM 1-Wire Alternator, 140 Amps, Stealth Black
At CVF Racing our alternators are specifically designed to work with pulleys at low RPM so you can be certain that your alternator will charge throughout the RPM range. A lot of high amp alternators just shift the RPM range higher to get more power at the expense of low end charging. (Kind of like a really big cam)
We use high quality insulating materials to keep your alternator running at high amps. You don't want to trust the performance of your charging system to a cheap alternator from overseas.
