XDP XD356 Wrinkle Black HD High Output Alternator – 1999-2003 Ford 7.3L Powerstroke

Upgrade the charging system in your 1999-2003 Ford 7.3L Powerstroke with the XDP XD356 HD High Output Alternator. Factory alternators can quickly become overwhelmed by aftermarket accessories like auxiliary lighting, stereo systems, plows, horns, air compressors, and other high-draw electronics. The XDP HD Series delivers a substantial increase in output so your electrical system can keep up without strain.

This brand-new, direct bolt-on unit produces 200 amps peak and a strong 130 amps at idle, giving you reliable power whether you’re idling or on the highway. The durable wrinkle black finish improves under-hood looks while adding corrosion resistance. Each alternator is pre-tested and ships with a results card. It installs using the factory mounting locations, factory belt, and existing electrical connections—no core charge required.
