390 Amp – 7.3L Godzilla

This SBC-F7.3-390XP High Output alternator is specifically designed, engineered, and manufactured for the Ford 7.3L Godzilla gasoline engine. It is a direct bolt in replacement for the OEM alternator with no modifications required. The 7.3L Godzilla engine began production in 2020 and can be found in Ford Super Duty trucks. The SBC-F7.3-390XP generates a maximum of 390 Amps at normal driving speeds and 220 Amps at idle.

The XP series of SBC alternators are manufactured in California, USA and assembled using DENSO components. This allows the XP alternator to tie into the OEM electrical system without any issues while producing significantly higher amperage at both idle and driving speeds. XP series alternators feature a larger housing while still retaining OEM fitment. They run cooler and are virtually indestructible.

A precision machined, hard anodized pulley made from Aircraft Certified 6061 aluminum is installed on each alternator for maximum output and durability.

This alternator comes with an unprecedented full two year warranty.
