        Comments about Proform 100% New, Chrome 1-Wire Alternator, Gm 100 Amp:

        First ProForm alternator wouldn't charge so ordered a replacement. Had to pay for the second alternator then get a refund on the first one after paying for both. Had a difficult time getting this alternator to fit my Suzuki Samurai and after a little over a year it siezed, chrome peeled off and was no good. I had to go back to the stock alternator even though I need more power to lift my snow plow. When the alternator siezed up it caused my fan to quit turning and my motor to over heat and blow a head gasket. Very poorly made alternator.

        Didnt fit my low mount because the case was different and had block and frame interference Looked good enough and the price was pretty good but was just to big since it didnt have the cut out like the alternator I was replacing.

              1937 Chevrolet Master Deluxe street rod equipped with two radiator fan, ac, halogen lights, 400 watt stereo, etc. - Replace a 65 amp alternator that was struggling to keep up with the demand and replaced it with the new ProForm chrome 100 amp. Easy installation, wiring and works great with no effort. I would purchase again.
