The 12-volt design, pulley configuration, and regulator setup make it a direct match for the specified Dodge Ram 2500 and Dodge Ram 3500 applications. If you are replacing a worn charging unit on a Dodge Ram 2500 or Dodge Ram 3500, part number 13766R provides the electrical output and hardware configuration needed for the listed fitments.

What It Helps Solve

• Low charging output from a failing alternator
• Battery drain caused by weak system charging
• Electrical instability under accessory load
• Noise or wear related to alternator pulley issues
• Replacement needs for the listed Dodge Ram 2500 and Dodge Ram 3500 applications

Installation Notes and Tips

Verify the existing unit type, amperage rating, pulley groove count, rotation direction, and regulator configuration before installation. Confirm fitment against the listed Dodge Ram 2500 and Dodge Ram 3500 applications, including the notes for Bosch or NDenso unit identification and production-date limits on 2001 models. Part number 13766R should be matched to the vehicle’s charging-system specifications before removal of the original alternator.
