Great Part at a great Price! Only thing to pay attention to is that this alternator is for the base model Ford Truck/Van/SUV that does not have the additional accessories... The part is an OE Reman Unit which fits perfectly and was easy to install!

I purchased the new for several more dollars instead of rebuilt. Perfect fit , works fine , a little pricey but I guess that's about what's going on in these times right now , everything is getting pricey. Got a lot of miles out of the old one , hope this one preforms the same. Thanks

Alternator itself seems decent enough. No complaints there. The voltage regulator it comes with is garbage. I had one fail about a year in. Took it in and Advance gave me a new one, so no complaints there. The second one always had trouble controlling voltage. It would charge fine, but my voltage would bounce at idle 0.5 volts or so. Finally got around the replacing the regulator with an HD version and no problems since. So, for the price it pretty good, and even with having to buy another regulator I'm happy.
