Performance Alternators and Starters


Performance cars may require more powerful starters and alternators to start and charge the vehicle as needed. Some performance starters and alternators are also designed in a custom chrome finish to match the custom dress-up kit you may have installed on your engine. O'Reilly Auto Parts has the high-output alternator or starter you need for your vehicle to complete a performance build or upgrade.

Performance Alternators

Upgrading your alternator can help ensure that your vehicle gets the power it needs for optimal performance. Depending on the number of on-board electronics or the size of your stereo system, you may need a high-performance alternator. If you notice your headlights dim as you operate your electronics or your stereo is not performing as designed, these may be a few signs that you need to upgrade the alternator. Performance alternators are built with heavy-duty components to provide additional durability while meeting and exceeding the electrical needs of your vehicle. We offer a variety of different alternator amperages, up to 160 Amps, to ensure you have the power you need to keep your vehicle running at its best. Find the performance alternator you need for your vehicle at O'Reilly Auto Parts.

Performance Starters and Starting System Parts

When you upgrade your engine to be more powerful, you should also consider upgrading the starter at the same time. Because performance engines are normally designed with higher compression, a stock starter may have difficulty turning the engine over and getting the pistons to move quickly enough to achieve combustion. Performance starters are designed with higher torque and more RPMs to deliver the power you need to start your vehicle. Installing a performance starter on your vehicle can help make starting easier so you can enjoy the drive.
