High Output Alternator for GMC Canyon (2009-2010) 5.3L

This 300 amp high output alternator is built for the 2009-2010 GMC Canyon with the 5.3L V8 engine. It delivers more charging current than a typical factory alternator, making it a strong choice for trucks running extra lighting, audio, winches or other high-draw accessories.

Why Upgrade to a 300 Amp High Output Alternator?

Higher output means more current available for everything on your Canyon's electrical system at once: factory equipment, added accessories and battery charging. That headroom is the main reason to choose a 300 amp alternator over a stock-rated replacement.
