Ford Type 5.4L V-8 Gas Engine High Output Alternator Upgrades

Upgrade the Small Case Alternator on Your Ford F-Series Truck, E-Series Van, or Expedition; As Well As the Lincoln Navigator

The 5.4L V8 is a member of the Modular engine family first introduced in the redesigned 1997 Ford F-150 as a Triton V8. The original engine produced in 1997 had a cast iron block and 2-valves per aluminium cylinder head. It was used in Ford's F-150 truck (including the performance Lightning Series beginning in `99) and Expedition from 1997 till 2004. Ford's E-Series Van began using the 2-valve model in 1997 as well and continues to do so. In 2003, the 3-valve model replaced the 2-valve on the F-Series and Expedition. A 4-valve model was used on many of Ford's performance and foreign vehicles, but stateside its most common application was in the Lincoln Navigator, which slowly phased over to using the 3-valve model in 2003-04.

The 3G series was most commonly used in early 5.4L Triton V8 vehicles. This includes the 1997-2001 Ford F-series Trucks, Lincoln Navigators, and the Ford Expedition. The E-Series van used the 3G exclusively from 1997 till 2004, and next to the 6G series from 2005-2008. Our large case 3G series alternator fits directly in place of the standard stock small case alternators used on the E-Series vans until 2004, and on the F-Series Truck until 2002.

It is used exclusively on 2002 to 2004 Non-Lightning, Ford F-Series trucks, as well as Lincoln Navigators and Ford Expeditions after 2002. The most common 6G series mounting styles for the 5.4L Triton V8 are either the 8253M Power Stroke style mount, or the 8303M Expedition style mount. The 6G was also used on E-Series vans from 2005 till 2008, when it was replaced by Denso and Mazda alternators. Read more about our 6G series, large case alternator here ( .
