      Repair Kit. High mileage and/or racing can wear out an alternator long before other major electrical parts fail.

      Kit Includes. Each PA Performance Repair Kit comes with a new voltage regulator, new brushes and bearings. Note this is not a full “rebuild” kit (of windings and other major components), but a replacement kit for high wear items.

      Application. This PA Performance Alternator Repair Kit is designed for OEM Ford and PA Performance 4G Series Alternators. Fits 1996 to 2001 SVT Cobra and 2003 to 2004 Mach 1 Mustangs that are equipped with a 4G Alternator.

        it worked

        took a couple of hours to put in, and it was a PIA to do. However once I got the Alternator out it was simple and cheaper than a new alternator. Do not believe the youtube videos on how easy it is if you have a Mach 1. However if it every goes out I would replace it again myself. 2003 Mach 1

        5 1998 Cobra - Ken

        Cured my charging issue.

        This issue was hard to pinpoint. Sometimes the alternator would charge and sometimes it wouldn't. My battery was 6 years old, so I replaced it first. Was still getting erratic charging. I decided to give this regulator kit a shot. Cured the issue. Three weeks of daily driving and I'm getting a steady 14.3 volts.

        5 1999 Cobra - 3B99SVT

        PAPerformance performs

        My lights were flickering on my '99 Cobra and the voltage would go above 15V. The PAPerformance voltage regulator and brushes installed perfectly. I did not install the bearings (yet) since my alternator is still quiet. My lights are no longer flickering and the voltage is holding between 14.0 - 14.6V, like it should. Much cheaper than buying a new alternator.
