Powermaster Race Alternators

4.52 out of 5 stars 106 Customer Reviews

Powermaster race alternators supply horsepower for your ride by ensuring the electrical and ignition systems have enough voltage to operate properly. This means your battery stays fully charged and predictable—you don't have to worry about your car not starting at race time. They feature a variety of high-amperage ratings, one-wire hookup, a gold battery post, and a heat-dispersant coating. Some models also include a pulley. Order the alternator designed for your vehicle application.
