Battery was strong enough to get me back 10 miles towing, so it wasn't a bad battery. Less than 5,000 miles on alternator. Will be exchanging/returning.

The first one I received had a broken electrical connector. The second one didn't fit right, I don't think the voltage regulator is the same size as the original Bosch unit. This is the second or third re-built junk alternator I've put in this truck from Advance. It works, though it runs a little high on the voltage. We'll see how long this one lasts.

I think this might be for the diesel engine but it shows to fit 6.0L. look at the connector in the picture and compare it to yours before buying. if you have a pin connector your probably looking for 321-2128.

Reman'd in Mexico, lasted less then a year, took it back for Warranty, they said it wasn't covered . . . Sad part is a took out the OEM "working" Alternator as preventative maintenance as she had 80,000 miles on it, this one lasted less then 20, should have left the OEM, went with new this time.
