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 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 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.

Word On The Trail

This company has always been the go-to site for good deals, good products, and service. I never have had problem with the products sold, even after several years of use. For example I have had the tire rack on my jeep from 2003 to now, I have brought a new jeep and the first thing I ordered was a new rack from them for my new jeep. Good product, good service, and the best prices. I use this company as a base line to compare other dealers with, and this company always wins out.

I have always loved the outdoors and with my camping experiences, it brought me into the Jeep world. It has always been a dream to own a Wrangler of my own and recently I was able to acquire one of my own! We’ve already been off roading and camping, and each time I come up with a new mod to do when ...
