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.
