      100% New. This Powermaster 200 Amp Mustang Alternator is 100% brand new, not re-manufactured like other companies sell and is fully tested at the time of assembly. It comes complete with internal voltage regulator and 6 groove serpentine pulley. A 200 Amp alternator will increase the charging capacity of your Mustang at all RPM Ranges.

      More Power. The Powermaster Alternator produces 130+ amps at idle (2000 alternator shaft RPM), and 200+ amps at maximum (6000 alternator shaft RPM). It is required to upgrade the main power wire because this alternator has a higher output than stock.

      Powdered Coated Finish. This Powermaster Alternator not only improves your Pony's power, but it also improves your Mustang's under hood appearance with an aggressive baked on black powder coated finish.

      Peace of Mind. Why waste your time and money rebuilding your old alternator again and again when it will only fail, replace it with a brand new high performance alternator from Powermaster for peace of mind.

      Application. The Powermaster 6G Series Alternator is a direct fit replacement with no mounting bracket modifications required to be installed in a 1999-2004 GT Mustang. The stock belt can be used on original equipment vehicles.

        Pretty good buy

        Needed a higher amperage alternator for my mustang to supplement my new amp install. Good product, no issues. Will be replacing soon with a higher output specialty alternator.

        3 2001 GT - Xylocor Installation Time: Less than 1 Hour

        Worked well for short period.

        Quality of alternator worked well for about 500 miles.. it's at powermaster now currently being repaired said it was over spun. But I'm running stock pulleys, no forced induction or even cams. I have cams but not been installed yet. Said the internal fans were twisted. So for now stock alternator back on, it was bought mainly to improve my underpowered look plus the extra amperage. American Muscle did their part it just a 3 due to the issue with the defective product.

        so far so good

        puts the power out and looks awesome under the hood. The BBK aluminum pulley did not fit however. So I had to use the super heavy pulley that came with it.

        Powermaster Alternator

        I had this installed along with the power cable upgrade and a new engine (by a certified mechanic) and the alternator overcharged and fried itself. The power cable connection at the alternator was melted like a candle. My advice, don't buy this overpriced alternator. The shop owner says this is the second time now that he has seen a powermaster alternator fry itself.

        I didn't think that adding a new alternator would make such a GREAT difference in ZIP!!!!!!!, My 1999 mustang GT is supercharged and that added juice really brings it to life a VERY noticeable improvement over the stock alternator!!!

        Great Alternator!

        The stock alternator had problems keeping up with the stereo that I have in the car. After installing this alternator, I haven't had the headlight dim at all. On top of the great performance, it really looks awesome! Really ties all the chrome items under the hood together.
