I want to eventually run a HF ham radio, along w/ tons of other accessories (audio, ham radios, winch, etc). 160 amp would be awesome!!

Thanks guys.

I was actually just researching this same topic last week. From what I gathered, the alternator the OP is talking about will not fit earlier model TJ's. It looks like the mounting bolt pattern changed.

If you have a '99 TJ 4.0L and want a 160amp alternator. (cross check your part numbers to see if this will work for other year TJ's)
Look for an alternator from a 2002 Dodge Durango 5.9L V8. I talked to the forum member that did the swap and he said it is a direct bolt in. The only difference is that there is an extra groove on the pulley of the durango alternator. So you just won't use the goove that is farthest from the alternator when you put your belt back on.

I ordered mine from Advance Auto last week and it should be here in the next few days. I'll verify that it fits when I get it in the mail.

I got a 136amp I believe from a v8 grand cherokee (don't know what year)... yes they work with a 97. You have to be careful when looking because some alts will randomly be lower amps. Mine went out on a trip so I had a guy at autozone search a bunch until he found one with the same bolts that was higher amps, only difference was the housing is bigger.

I researched this far and wide before I did it. I used to have a sheet with about 40 alts that would work but it seems to have been lost.

However google does help: http://www.bc4x4.com/tech/2004/jeepalt/

Couldn't you just use the pulley from your original alternator?

From what I have read you could swap pulleys if you wanted to.

When I go to swap the alternator I will just leave the durango pulley on it, so it is less work.

That's the exact write-up I have...I snatched it from Pirate from Firetoad like 4 or 5 years ago. Good now I don't have to host it somewhere it's already right there. And yes, he had a 97 4.0L TJ and put a 136 amp alternator on it, so I know it works on 97's. Anyway there it is. I also have that same file in PDF form now if anyone wants it.

Thanks for posting that link that saves me lots of headaches now.

YES! After a little searching I found my post.

This topic is talked about a lot, you just have to find the right thread/info.
So I did a little searching for you guys and this should be more than enough info.

Here's the thread
Here's what you have
Here's the perfect swap for your 97-02 (but, as mentioned, there will be and extra groove in the pulley)
And this is a big list of alts if you want to choose your own

Is there a down side to a higher amp alternator? All else being equal, it seems the higher amp alternator would sap more power from the engine. Does anyone know if the difference would be noticeable?

No noticeable difference in engine strain, and there is no other down side that I've ever come across.
Your volt regulators will handle everything just fine, and your volt gauge will stay more stable when running multiple accessories.

Yes, it looks to be plug and play for my Jeep. Although, I haven't had a chance to put it in yet. The mounting holes on my alternator are at the 12 and 6 o'clock position.
I think your 2006 has mounting holes at the 2 and 6 o'clock position so check to make sure it will work before you order it.

Maybe Pirate has a thread on this but, do we need a direct "plug n play" thread?

Mine is an '03 TJ. A '98 Durango's V-8's 160 amp is a direct fit on my '03. No counting grooves, belt or pulley changes.

Is 03-06 the same set up?

I really don't know, Bro. I would suspect so but, can't tell you that. I would recommend a search on ROF.com under the TJ section. BTW, they are very non Rubi friendly.
