Aeagle Alternator for Ford F-150, Expedition & Lincoln — 110A 2004–2008, 6-groove CW Direct-Fit

Aeagle’s direct-fit 110-amp alternator replaces worn units on compatible 2004–2008 Ford 4.6L and 5.4L engines for reliable 12V charging and plug-and-play installation.

Designed to meet factory mounting points and electrical specs, this Aeagle alternator is built as a like-for-like replacement for several Ford part numbers. It’s engineered with a clockwise rotation, an internal regulator, and a six-groove pulley to match the original equipment on many F-150, Expedition, Lincoln Mark LT, and Navigator models. Every unit is validated under high thermal and high electrical load conditions to help ensure durability and consistent charging performance under normal driving conditions.

Will this alternator fit my Ford F-150 or Expedition?

If your vehicle is listed among the compatible applications, this alternator is made to bolt in without modification. It matches the factory dimensions, pulley class, rotation, and electrical connector layout intended for those model years.

• Fits Ford F-150 2004–2008 with 4.6L or 5.4L V8 engines (not for SVT Lightning).
• Fits Ford Expedition 2005–2006 5.4L V8 with standard equipment.
• Compatible with Lincoln Mark LT (2006–2008) and Navigator (2005–2006) 5.4L V8 models with standard equipment.
• Replaces many OE numbers including 4L3U-10300-BA/BB and 5L7T-10300-CB variants.

How does the alternator meet electrical and mechanical requirements?

This unit provides 12 volts at 110 amps with a clockwise rotation and an internal regulator, matching the electrical output and control behavior of original equipment. Critical dimensions and mounting points are measured precisely to allow direct installation and correct belt alignment with a six-groove (S6) pulley.

• Voltage: 12V; Amperage: 110A for typical accessory loads.
• Rotation: clockwise (CW) and pulley class S6 to match serpentine belts.
• Includes internal regulator (IR) and integral fan type (IF) for cooling.
• Clock position: 10 o’clock electrical terminal placement for proper fitment.

What quality checks and standards were used on this replacement?

Aeagle subjects each alternator to high-heat and high-load testing to evaluate durability and thermal resilience. Contact surfaces and electrical connections are inspected, and units are balanced and tested for output under simulated driving conditions before shipping.

• High thermal environment testing to simulate engine bay heat.
• High power demand cycles to verify sustained output capability.
• Dimensional inspection for precise mounting and alignment.
• Electrical tests confirm regulator performance and output stability.

Who is this for: This Aeagle alternator is intended for owners or technicians replacing a failing or underperforming alternator on compatible Ford trucks and SUVs from 2004–2008. It’s best for those who want a direct replacement that matches factory electrical characteristics and mounting dimensions, including DIY mechanics, independent repair shops, and fleet maintenance managers seeking a reliable, tested aftermarket alternative to OE units.
