Your alternator uses small wires within a magnetic field to induce an electrical current from your truck's mechanical output. Without the proper voltage, your accessories are unable to function. With our performance alternator GMC C1500, you get up to 14.8 volts of output to keep your battery consistently charged. Plus, the high-quality brushes carry a smaller field current, so they last longer and perform better than stock options. At AutoZone, we make maintenance easy and affordable by providing free battery charging at any retail store, as well as Same-Day Store Pick-up when you order your GMC C1500 alternator online.
