Quick response from seller:
"the stator, rotor and diodes have been upgraded."
D2s (and Bosch P38s) get the tach signal from the ECU so the pulley size shouldn't affect it.That makes sense. There are also pulleys of two different sizes - IIRC, P38A one is smaller in diameter, so you could squeeze more juice out of alternator at lower RPM (but your tachometer will no longer read correctly).
Didn't know - then a smaller pulley is a bonus.D2s (and Bosch P38s) get the tach signal from the ECU so the pulley size shouldn't affect it.
Yep it is stock, then rebuilt with higher AMP hardware. When I had an 05 Rubicon I found out a Durango alternator was 160amp vs a 130amp in my Rubicon. Cheap & simple upgrade, and online or rebuilt locally it could go up well past 200AMP and MUCH cheaper vs a Mean Green Alternator.
I've actually been to their facility, and it's one of the strangest places I've ever encountered.

ok boys, you got me thinking for a while.
To get the same alternator to produce 40% more current, you need slightly more than a new diode pack.
The stator winding should be able to support higher current; the existing one _may_ live through some short bursts of high output, but if you draw that much on a duty cycle higher than normal, you'll have a meltdown.
....With my old 130 amp, When I used the winch the truck would want to shut off and voltage would drop to 12.8ish..
This is interesting. I have a factory original alternator on my D2, and I've never had any running issues or significant voltage drops with the winch running.
Come on, even an old-school external linear voltage regulator barely consumed a few watts (they didn't even have any sizable heat sinks).I think most modern voltage regulators use a switcher instead of a linear regulator, so that's got to be good for 10-20% efficiency increase and makes RPM a lesser weighted factor. Does anyone really need a 200 amp alternator if the 100 amp is capable of generating full power at near idle?
