Dual 125 amp alternators

The dual alternators, at 125 amps each, can help power your Silverado® 2500HD through a variety of uses, from long, heavy-duty days on the work site to road trips with a camper in tow. Your truck can deliver a sustained power output without sacrificing the ability to turn over the battery. Dual alternators are included with the available Duramax® 6.6L Turbo-Diesel V8 engine.
