MPA Electrical 15431N Alternator

110-Amp Alternator for Ford Applications

MPA Electrical 15431N is a new 12-volt alternator built for Ford charging-system applications that require a 110-amp output, internal regulator, and internal fan. It uses a 6-groove serpentine pulley, clockwise rotation, and a 9:30 clock position for proper mounting and electrical alignment.

Compatible with select Ford F-150, Ford F-250, Ford F-250 Super Duty, Lincoln Mark LT, and Ford F-150 Heritage applications, this alternator supports direct replacement needs where OE-style fitment and electrical specifications matter. Part number 15431N also cross-references BBB Industries 8318 for the same application.

Detailed Description

MPA Electrical 15431N is an alternator engineered around Ford charging-system specifications, including a 110-amp rating, internal regulator, and internal cooling fan. The 6-groove serpentine pulley and clockwise rotation help match the original accessory drive layout, while the 9:30 clock position supports correct installation alignment in the engine bay. This unit is a practical replacement choice for Ford F-150 and Ford F-250 platforms, as well as Lincoln Mark LT applications that use the same alternator configuration. The part number 15431N is also referenced against BBB Industries 8318.

MPA Electrical’s New line identifies this as a new replacement component rather than a remanufactured unit, making it a straightforward option for restoring charging performance on 2004-2008 Ford F-150, 2006-2008 Ford F-250, 2006-2008 Lincoln Mark LT, and 2007 Ford F-250 Super Duty applications with the specified regulator plug configuration.
