    48550 - Powermaster GM High Output Upgrade Alternator is rated 5.0 out of 5 by 3.
    Rated 5 out of 5 by from Seems Solidly built purchased this because my stock 125 amp alternator was not keeping up while plowing snow. This alternator made all the difference in the world, along with the recommended heavy duty battery cable replacement..
    Date published: 2021-02-02
    Rated 5 out of 5 by from Good investment Bought to increase power output and add custom stereo. Works and looks great. Wish it came in all black though.
    Date published: 2019-09-12
    Rated 5 out of 5 by from Awesome output Just installed this yesterday in my 07 Avalanche LTZ and it’s incredible! My voltage gauge used to be around 12-12.5 running. Now she is going up to 14.5! Well worth the money. And you can still use the stock serpentine belt. Just make sure to follow the instructions and use a 2 gauge wire to handle the extra amps! Plus I had called Powermaster because I had a few questions because this was my first time installing an alternator. Their tech dept is friendly and knowledgeable! A+++++++! Don’t waste your money on any other brand!
