An alternator charges the battery and provides power to your vehicle's electrical systems. If you have a custom vehicle with extra accessories like a high-end stereo system or other on-board electronics, you may need to upgrade your alternator. A stock alternator that is not producing enough voltage may cause dim headlights, poor stereo system performance, or it may wear out prematurely. It is also important to upgrade your grounding strap and charge wire to handle the additional amperage. O'Reilly Auto Parts carries performance alternators, ground straps, and related parts for all your electrical performance needs.
