Description Overview
It goes without saying, but the alternator is the lifeline to keeping your Duramax on the road. With all of the aftermarket electrical upgrades you can make, such as lighting, winch, and stereo, the factory alternator is severely tasked and not always able to deliver a consistent charge. Ensure your system maintains proper voltage by upgrading to this replacement alternator from Powermaster.

About Powermaster Performance Starters and Alternators
The two most important electrical components of your truck are the starter and the alternator. One gets it running, and the other keeps it running. Over time, these can begin to degrade and require replacement, and when that time comes, make sure to give your truck a big upgrade by going with the trusted name of Powermaster. These are designed as a direct replacement for a simple installation, but deliver big gains in power so you'll realize easier starts and better charging, no matter how many 12 volt accessories you're running.
