320 AMP High Output Alternator

The Sinister Diesel 320 AMP OEM High Output Alternator is engineered as a robust upgrade for 1999-2007 Ford Powerstroke 6.0L and 7.3L trucks. This alternator delivers a substantial 320 amps, ensuring that even with demanding accessories like high-powered lighting, audio systems, or winches, your truck's electrical system remains fully charged and operational. It maintains over 200 amps of output at idle, preventing battery drain during stationary use. Constructed with a CNC Billet Aluminum chassis and finished in a signature Sinister Blue, this alternator is built for longevity. Key internal components include upgraded high-output regulator, high-temperature bearings, advanced 6-phase hairpin stator technology, twin rectifier plates, and 12 massive diodes. It comes with a 1-year warranty. A critical warning is noted: because this alternator exceeds OEM specifications, a High Amp Wiring Upgrade Kit must be purchased concurrently. Failure to do so will void the alternator's warranty and may cause damage to the factory wiring harness. The Fitment list includes detailed applications for Ford F-250, F-350, and Excursion models from 1999 through 2007 with either the 6.0L or 7.3L Powerstroke engines.
