The alternator on my '05 F250 6.0 has died.

What are the pros & cons of replacing it with a Ford rebuilt unit vs one from NAPA?

There are a bunch of threads on here about alternator quality -- and a group buy where some alternators were bench tested and didn't deliver the goods claimed.

A lot depends on what you are doing --- are you using heavy electrical loads?

Or a straightforward application.

If I were replacing mine, I would buy the largest commonly available alternator that would fit and deliver the power I need over the RPM range I intend to operate in.

There are specialized alternators for audio, welding, etc. that would drive the cost way up, but deliver commensurate performance.

One of the best "tricks" is an outboard diode / electronics package.

So tell us more as to what your needs are...

 

This is the unit I put in my truck an in made a BIG difference.
