It comes complete with internal voltage regulator and 6 groove serpentine pulley. A 225 Amp alternator will increase the charging capacity of your Mustang at all RPM Ranges.

More Power. The Powermaster Alternator produces 100+ amps at idle (2000 alternator shaft RPM), and 225+ 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.

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.

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 ...

    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.

    Review from Powermaster Alternator - 200 Amp Black (99-04 GT)

    Easy installation (woman approved)

    Easy installation! Came quick. Better idle. (Not anything extremely noticeable but it didn't do any harm which is always a plus.)

    Review from Powermaster Alternator - 200 Amp Black (99-04 GT)

    Keeps Power to Your Engine At It's Peak

    I purchased this mainly to insure that maximum amperage and power was being delivered to my ignition coil on plug packs and fuel pump at idle and under load. I also have an aftermarket stereo head unit and wanted to insure that there is no power loss to the headlamps when in use. When the alternator arrived it was well packed with injection foam packets to make sure that there was no movement during transport. The alternator also came with a proof of performance certificate what showed when the date it was tested, power reading at idle, simulated cruising rpm, and maximum rpm and maximum voltage delivery. It gave me confidence in knowing that the alternator was ready for high demand use. Install was quick and easy with basic hand tools. It took me less than 15 minutes to do the work. I previously purchased a power wire from AM to protect the electrical system and handle the increased supply load. Acceleration is much smoother and the instant of hesitation that I was previously experienced went away. I feel at a minimum that an owner should upgrade their power wire and alternator to insure that you are getting peak electrical power and performance out of your car. This alternator will be ready to handle additional mods as you build your car. You can't go wrong with this investment.

    Review from Powermaster Alternator - 200 Amp Black (99-04 GT)

    looks great works well

    Looks great under the hood, and preforms well. Took about a good 2 hours to install with the added and needed power cable, spliced it in with the original wiring harness so it look pretty much stock.

    No more power loss

    This product helped with power loss at idle when running air conditioning and other accessories. Take off is more smooth from a stop.only had it in for a week or two good so far.easy install exact fit no problems.

    Review from Powermaster Alternator - 200 Amp Black (99-04 GT)

    POWWWWWEEERRR!!!!!!!

    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!!!

    Review from Powermaster Alternator - 200 Amp Black (99-04 GT)

    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.
