Not worth the extra $$ in my opinion
Purchased this from XDP 10/20/2019 invoice # 1643677A. The mean green alternator gave out on me 1/27/23 so at the $370 I paid in 2019 it cost me over $120 per year to maintain my batteries. If these are only gonna last a couple of years I'll just keep using re-mans at less than half the price. I don't see the value at the price for these things. 3 stars. one for each year it actually worked.

So far so good - 1888552
The alternator arrived very well-packed and looks to be of very high quality. Installation went very smoothly and my system is charging as expected.

Startup is better and no more dimming lights. Can’t wait to see how it performs in the winter. 2007 Dodge Ram 2500 5.9
