1. Cost: The Bosch AL6454N alternator is more expensive than the stock alternator. This may be a consideration for those on a budget.

3. Compatibility: While the Bosch AL6454N alternator is designed to fit Dodge Ram 2500, 3500, 4000, and 5.9L Cummins engines, it's important to double-check compatibility before purchasing.

Just be sure to double-check compatibility and consider the cost and installation requirements before making a purchase.

Details:

I kept having electrical dimming so thought had a faulty alternator, replaced it second time with another new one. Estimated 1 year of use on the alternator. Turns out I have a faulty voltage regulator in the PCM. For sale is an alternator that came out of a 1996 Ram 2500 with the 5.9 Cummins.

This alternator is fine and confirmed testing at 14 volts .
