    XDP XD357 Wrinkle Black HD High Output Alternator – 1994-1997 Ford 7.3L Powerstroke (OBS)

    Upgrade the charging system on your 1994-1997 Ford 7.3L Powerstroke with the XDP XD357 HD High Output Alternator. Factory alternators often struggle when you add aftermarket accessories such as off-road lighting, snow plows, upgraded stereos, air compressors, winches, or other high-draw electronics. The XD357 delivers a substantial increase in output so your electrical system can handle the extra load without strain.

    Key Features:

    • 200 amp peak output
    • 130 amp output at idle
    • Direct bolt-on installation using factory mounting locations, belt, and connections
    • Durable wrinkle black finish for improved looks and corrosion resistance
    • Brand new unit — no core charge required
    • Pre-tested with results card included

    Fitment: 1994–1997 Ford F-250 / F-350 with 7.3L Powerstroke (OBS)

    Important Note: Some 7.3L OBS trucks came with an 8-rib belt instead of the more common 6-rib. If your truck has an 8-rib belt, you will need to swap the pulley from your original alternator onto the XD357.

    Warranty: 2-year / unlimited mileage manufacturer warranty

    The XDP XD357 is a straightforward, high-output upgrade that keeps your OBS Powerstroke’s electrical system reliable while supporting modern accessories.
