Sinister Diesel 320 Amp OEM alternators are trusted by many Diesel repair shops and stores to be the “fix all solution” for the Ford Powerstroke 6.4L alternator failures which may cause electronics failures due to low voltage from the lack of alternator power that comes from the Ford factory. Sinister Diesel's proudly uses brand new OEM alternator components such as the Stator, Rotor, Rectifier and Regulator to give our customers piece of mind to match our standard of quality. Our alternator will be a direct fitment without any modifications needed. We can proudly stand behind all of our alternators with a 1-year warranty.
