An alternator provides electrical power to your Wrangler when it is running. It also recharges the battery, which is needed to start the engine. Because they often have greater electrical needs than regular passenger vehicles, alternators for Jeep Wrangler JKs must work a bit harder. These high-output alternators supply more power and will not drain your battery, as regular alternators may if they have insufficient electricity. When adding auxiliary lighting and other Jeep Wrangler lighting accessories like light bars and mounts, it is often advisable to replace your stock alternator with an aftermarket alternator. Affordable and easy to install, these powerful parts will keep you from being stranded with a dead JK.
