• Also fits: Ford Expedition (2005–2006) 5.4L, Lincoln Navigator (2005–2006) 5.4L, Lincoln Mark LT (2006–2008) 5.4L.
• Not compatible with SVT Lightning or vehicles with nonstandard equipment options.
• Cross-references: AFD0110, 4L3U-10300-BA/BB, 5L7T-10300-CB and other OEM/service numbers listed.

How does the alternator perform under load and in hot conditions?

The unit is tested for high thermal environments and heavy electrical demand to ensure the alternator maintains stable charging across common driving conditions. With 110 amps of output and an internal regulator, it supports accessories, ignition, and battery charging without excessive voltage fluctuation.

• Output: 12V, 110A for sustained electrical supply.
• Regulator: Internal (IR) for simplified wiring and consistent voltage regulation.
