Detailed Description

WAI 13302N is a direct-fit style alternator for select Dodge Ram and Dodge truck platforms that require a 120-amp Denso unit. It is listed for 1994-1998 Dodge Ram 2500 and Ram 3500, 1997 Dodge Ram 2500 Van (Mexico), and 1990-1993 Dodge D250, D350, W250, and W350 applications. This part cross-references BBB Industries 13302 for the same application.

Built as a new replacement alternator, the 13302N uses proprietary components and manufacturing processes to support long service life and stable electrical performance. The included pulley, serpentine belt groove count, and external regulator configuration make it a practical replacement when restoring charging output on Dodge Ram 2500, Dodge Ram 3500, and related truck models.

What This Alternator Helps Address

• Low charging output at idle or under electrical load
• Battery warning light caused by alternator performance loss
• Dim lights or unstable accessory operation
• Charging-system failure on high-demand Dodge truck applications
• Replacement needs for worn or failed Denso-style alternators

Installation Notes and Tips

Verify the vehicle’s original alternator family, amperage rating, pulley groove count, rotation direction, and regulator type before installation. This unit is listed with an external regulator and an 8-groove serpentine pulley, so matching the original charging-system configuration is important for proper fitment on Dodge Ram 2500, Dodge Ram 3500, and related models.
