    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 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.
