        5 Top Rated Questions

        Can you tell me what size belt I need with this alternator, 2.76 on eaton, extra idler pulley, and stock lower?

        • The PA Performance Alternator would reuse your existing alternator pulley, allowing you to retain the existing belt size.

        Helpful (5)

        The pulley is too big, does this need a different type of belt or the same one?

        • The stock belt can be used on original equipment vehicles.

        Helpful (0)

        Is there a pulley that comes with the alternator? And if so, how many belt grooves does it have?

        • I bought this alternator in May of 2015 and it came with a pulley. The pulley is a bit larger in diameter than the factory pulley so a shorter S/C drive belt may be in order. The larger pulley spins it slower than the factory alternator, but the faster spinning factory alternator seems to die early. Mine was dead after 5,000 total miles.

        Helpful (0) Show 1 more answer

        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.

        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.

            Fitment was good. About 3 hours to install so wasn’t too bad. Good product so far, it’s been on my car for about to weeks and working well.

            Excellent product

            Installed on Christmas 2018. So far so good. Very happy, made in USA, Pennsylvania. 100 new components. Pulley on my original was 2.75", pulley on PAPerformance 130 amp new 6G, 3.25". Same belt, didn't have to change size. Hopefully it will never overspin. Installed, fired the car up, was reading a good 14.5 volts. Great company, great product, great dealing with AmericanMuscle, totally great experience.

            Been having it on for a couple of weeks now and it works great, install wasn't to bad, I did as the guys recommended to remove the bracket and since I'm a little big I also removed the tire.

            PA Alternator 130 amp - works great!

            Great Alternator and very pleased so far. I replaced 2 alternators (rebuilds from local auto part stores) in less than 2 years.This PA Alternator comes with a larger pulley also to help prevent premature wear from over spinning. Spend the money for the PA upgrade and you will not be upset. I also purchased the upgraded power wire. Both products work very well. Thanks AM!

            Good alternator

            Had to replace the factory alternater due to failure. The install was a nightmare and I had to purcase a bigger belt due to the larger pulley size on this versus the stock alternator, but this does a great job at keeping my battery charged.

            Broken Case and Doesn't Spin Freely

            The alternator was damaged, the casing is cracked and some of the metal vents are broken off. It also does not spin freely, it keeps catching something while trying to spin.

            Awesome alternator does what it says. I install a lot of additional electrical equipment in my car and this alternator generate enough power that nothing dims and the battery stays charged really well. Definitely recommend.

            Better than stock

            I bought this alternator in May 2015 due to a dead factory alternator after only 5,000 total original miles. I love My mustang, but not a big fan of Ford because this problem is far too common with the Terminator. The installation took me a leisurely 2 hours. No big deal really other than I've NEVER had to replace an alternator from under the car, as required by the Termi.

            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.

            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.

            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.
