    57294 is rated 5.0 out of 5 by 3.
    Rated 5 out of 5 by from Great Alternator Well built alternator. I upgraded from a Jegs 100 which is also a great alternator but had a hard time keeping up with 3 cooling fans, fuel pumps and all the added electronics that’s need added over the years. This Powermaster 150 amp is a charging animal. It maintains 13.8-14.2V at idle now. The car even runs better now that it’s getting proper amps and volts to everything.

    Rated 5 out of 5 by from Works great! Very happy with this alternator, I prefer the sleek black look over chrome, it runs very quiet, and provides plenty of amps even at idle. Be sure you upgrade to a 6gauge wire feed when running this alternator.
