Stock alternators can only keep up with so much electrical demand that we require from our Duramax trucks. This high output alternator is the answer to your charging problems. Fits in the stock location and cranks out 200 amps, perfect for high output applications. With this single high output alternator, there is no need for a dual alternator setup. You can even keep your stock serpentine belt and not worry about getting different sized belts like a dual alternator setup requires. This alternator's tool steel rotor shaft is supported at both ends by heavy duty double sealed bearings. Great replacement for trucks that have extra accessories requiring extra amperage.
