        Works but whining noise

        Absolutely no clue why this brand new alternator would be whistling/ whining already for my Jeep I even put a screwdriver on the alternator and my ear up to it and can confirm it’s the source but it works perfectly fine keeps steady charge for my sound system and extra lights but definitely concerning me about the noise

        Perfect for anyone with a Winch or Light bars

        This Alternator is perfect for anyone with light bars or running a aftermarket stereo system. The alternator puts out plenty of power to keep up and you never have to worry about your lights dimming.

        Perfect fit...easy install!

        I am only a novice weekend mechanic, but was able to remove the 25-year-old original alternator on my 1992 Wrangler YJ and install this new alternator with ease in less than an hour. It runs fantastically, with 30 more power than the OEM.

        Saved my Project

        The PA Performance Alternator saved my whole project from being scrapped. My alternator broke on me in the middle of the day and I needed one by the weekend or I would have to scrap the car. Now my Jeep is running perfectly and has never been better! Highly recommend this product

      I have a 97 2.5L and I'm considering upgrading to accommodate a winch and some off road lighting ... if I upgrade to this alternator, will I also need to get a different belt, or does it fit without needing to upgrade that too?

      • You would use the stock belt. We would recommend upgrading the wiring and the battery as well.

      I have a 1994 4 cyl wrangler with a stock alternator. The front end has a 12K winch. Should I put on a larger alternator and if so what will I need to go with it, I am only running 2 extra fog lights. Thanks SidG

      • It would not be a bad idea to upgrade your alternator or use a dual battery set up with a winch! The PA Performance Alternator- 120A is a great upgrade option!

      I am in the process of upgrading my battery and alternator. If I go with a 120 amp alternator what gauge battery cable should I use? Should I go larger than 2 ga?

      • It is not necessary to change your cable with a 120 amp alternator, so you should be just fine with the stock one.
