Product Details

BBB Industries REMAN ALTERNATOR 13912 is a remanufactured charging component for vehicles originally equipped with a Nippondenso-style unit. The alternator is configured with a conventional pulley, internal fan, and air cooling to match the original electrical layout on supported Dodge Durango and Dodge Ram 1500 applications. This part cross-references 421000-0100 and 4801251AA for the same application.

Compatible With 2001-2002 Dodge Durango, N/A; 2003-2006 Dodge Durango, N/A; 2002-2006 Dodge Ram 1500, N/A. The 13912 alternator is a practical replacement when the charging system needs an OE-style reman unit with the correct pulley, rotation, and regulator configuration.

Common Uses

• Restores charging output when the battery is not staying charged
• Addresses dim lights or electrical load issues caused by weak alternator output
• Replaces a noisy, worn, or failing alternator assembly
• Supports vehicles showing charging-system warning lights
• Helps correct belt-drive charging problems on serpentine systems

Installation Notes

Verify pulley groove count, plug clock position, rotation direction, and voltage regulator type before installation. This alternator uses an external regulator and a 2-position plug clock, so connector and wiring match should be confirmed against the original unit. Always inspect the belt, battery condition, and charging circuit before and after replacement to confirm proper system operation.

Quality Assurance

BBB Industries remanufactured electrical components are built to replace original equipment units with application-specific fitment and configuration details. Part number 13912 is specified for select Dodge Durango and Dodge Ram 1500 models with the listed charging-system setup.
