3G Alternator?

I have heard people refer to a 3G Alternator upgrade. I assume this refers to 3rd generation. Have others heard of the same thing. What year of ford trucks would have this type of Alt? and what are the benifts?

Someone had a list on here of cars that it came in. I think several different ones did. Some bolt in, others need bracket modification. Some also need re-wiring.

The big benefit is that it will not burn your truck up like the 2G did. The 2G has a bad plug where the two 10Ga black with orange wires plug into the alternator.

The 3G has a stud instead of the plug and you have to put two crimp on connectors on the two 10Ga wires to the alternator. If you buy a 3G with more amps than stock then you will have to run larger wires and fuse link.

The 3g is one of the best alts ever made. It was in super duties till 04. The parts hold out real well. I have one in my 99 that I converted to 200 amp..There is a small and big version if I remember correctly.
