alternator pulley Does the alternator come with the pulley? Its not pictured.


  • The alternator does come with a pulley. Mine arrived with a 3.2" pulley, you may swap the the stock size but its not recommended due to higher rpm stress on the alternator.

PA 130 ALternator pulley I ordered a new alternator PA 130 for my 03 Cobra and it came with the 3.20" installed already, Do I have to swap the stock 2.60" alternator pulley or leave the 3.20" already installed, car does have the stock 7.5" crank pulley.


  • The stock (smaller) pulley is actually over spinning the alternator from the factory which is what causes these cars to have alternator issues so frequently. The larger pulley will lower the rpms of the alternator and still provide the correct amps especially for a relatively stock car not needing the higher output.

Will the larger pulley cause the drive belt to be too tight? Should I install a shorter drive belt?


  • Since it has a larger pulley than the stock alternator you will need a larger belt.

    A must have to make sure your Pony Starts to live another Day !

    The Factor Alternator went out, read all the good reviews on the PA Performance Alternator ,and order it .She starts right up with ease. The price was also a bit cheaper then the Local auto part stores . So why not pay a little less and get a New high Performance Alternator that is trusted in the Mustang World.

    Cobra alternator fix

    I purchased this alternator to replace my factory alternator that suffered an early death. Fit, finish, and function are equal to or above factory level.

    PAPerformance Alternator - 130 Amp (03-04 Cobra)

    This alternator does its job and more. American muscle hooked me up with a larger pulley size to help illeviate over spinning my alternator; which is a common thing with supercharged applications. Installation is easy, and will require you to get underneath the car. Great part and I highly recommend it.

    PA Alt

    Good upgrade,quality,and fit. Old alt tested bad and made battery light come one if cruising the city. It fixed the problem and it has no issues. You can install without the thicker gauge cable and if you need a longer length pa does make one.

    Good Quality

    Very nice quality from PA Performance. Just make sure you get the small metal sleeve off of your old alternator. You will need it to get your pulley to sit correctly. You don't need to remove the alternator bracket, just loosen the top bolt and it will come out.

    Great stock replacement.... So far.

    It has been working steadily so far (two weeks) since I installed it. The process it's self was almost a nightmare but that's just with any 03-04 cobra alternator. Other than that I'm satisfied.

    Perfect OEM replacement

    Why buy a remanufactured unit when you can buy this high-quality alternator. All new components so should provide me with years of service. Has slightly higher amperage rating than the oem alternator so it is perfect for mildly modded Cobras like mine.

    Good choice

    Installed on 03 cobra after over spinning factor Alt. Installation wasn't bad but, do yourself a favor and just remove the lower alternator bracket and you will have know trouble removing the alternator from under the car.
