Alternators & Alternator Kits
One of the most important systems in nearly every automotive application is the electrical system. It is required to start the engine, power the ignition, as well as lighting, gauges, HVAC, wipers, and other components in need of voltage. To keep the battery charged while driving, a charging system is required. The main component in the charging system is the alternator. This belt-driven component replenishes any power used by the vehicle while the engine is running. When additional electrical parts are added to the vehicle, more amperage is needed to keep up with demand. Performance alternators are designed to provide additional electrical power as well as a unique look to compliment the other engine components under the hood of your race or show vehicle.
