    Features & Details

    • 6G Alternator Repair Kit
    • Replaces High Wear Items
    • Includes Voltage Regulator, Brushes and Bearings
    • Designed for OEM Ford and PA Performance Alternators
    • Fits 05-08 GT Mustangs with a 6G Alternator
    Repair Kit. High mileage and/or racing can wear out an alternator long before other major electrical parts fail. That is why PA Performance created a repair kit to replace the high wear components that are prone to fail early. Designed to allow a you to replace those simple wear parts, this kit will breathe new life into your old alternator.

    Kit Includes. Each PA Performance Repair Kit comes with a new voltage regulator, new brushes, bearings, as well as new rear bearing tolerance rings that are destroyed at disassembly. 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 6G Series Alternators. Fits 2005 to 2008 GT Mustangs that are equipped with a 6G Alternator.

        So I bought this PA Alternator 2158WHO one year ago. The voltage regulator is now showing bad.... Figures just after the warranty expired... Will this repair kit work on this 2158WHO alternator?

        • Yes, this kit will work with that alternator as it is designed to work with both Ford and PA Performance alternators.

        is there an install video I can look at?

        • Unfortunately we do not have an installation video for this part. I recommend contacting the manufacturer for installation help or consulting a shop.

            Check charging system

            I had the "check charging system" message. I purchased this kit soley for the voltage regulator. After install (where i had to re-use the old tolerance ring) i haven't had that error message.

            Check Charging System

            Also works on GT500. I used this on the 6A Shelby Alternator without issue.

            Over Charging

            My alternator was over charging the system, running approximatly 15.94v according to the scanner. This kit came with everything I needed to get it back into the normal operating range. Very easy, straight forward install.
