High Output Alternator for GMC Yukon (2015-2018) 5.3L 6.2L

This 350 amp high output alternator is built for the 2015-2018 GMC Yukon with the 5.3L or 6.2L V8. It makes much more current than a typical factory alternator, so it's a strong choice for trucks running extra lighting, winches, upgraded audio or other high-draw accessories.

Why Upgrade to a High Output Alternator?

A factory alternator is sized for the stock electrical load. When you add accessories, a stock unit can struggle to keep up, especially at idle, and your battery makes up the difference. With 200 amps available at idle, this alternator helps keep voltage steady and your battery charged even in stop-and-go driving.
