Trailer lights, auxiliary lights and other electrical parts work best when there's a steady flow of voltage keeping your battery charged. An alternator for GMC Yukon provides an output between 13.5 and 14.8 volts, which is an ideal amount to keep your battery 100 percent charged. The alternator brushes carry a small field current to extend their functionality. AutoZone carries Yukon performance alternators at low prices and from the best brands in the industry, so you can bank on quality construction and long-lasting durability when you shop with us. Our Loan-a-Tool program and Same-Day Store Pick-up are great for when you need your aftermarket alternator as soon as possible.
