People are using one for a 2004 Durango 4.7L.
160 amps, drop in fit.

I have the threads saved at home, search i guess could find them.

It makes a difference what year TJ as to what year or model Dodge or Jeep GC is a match . They changed over the years . I think on my 99 I used one from a 98 Dodge Ram w/136 amp alt years back. Their is plenty already written about the swaps , Search tool is your friend.

I have posted a list of potential donors for 117A, 136A, and 160A units - the 117A should fit right in, the larger units will require grinding. Other pitfalls are noted, and the Cham/LSTR numbers given should be usable at any parts house.

If you are replacing your alternator with a higher-output unit, and expect to actually USE that capacity, consider a wiring upgrade mandatory.

Google 160AMP Alternator for TJ and you'll get ton of info. I actually read some on it this morning just for **** and giggles...

Rokmen TT, Rokmen control arms, Novak NV241 cable shifter, JKS 1.25" BL + 1" MML.

Anybody can take advice if it doesn't interfere with their plan.

I have 4 130w lights plus factory fogs and just headlights and fogs alone make my voltage dip bad. And I supposedly have a 117a alternator. I'll be taking it to test it tomorrow, just to make sure.

What Jeep do you have?

Filling in your profile would help to understand what your dealing with...

Judging by his username, I think he has an 06 TJ...

I have an 04 TJ and the alternator of the same year for the darango works great. There is an extra mounting hole that sticks out a bit that I have read you may need to grind off, but I didn't and it fits fine.

You are absolutely right and in his case we don't know if he has 4.0 or 2.4 which I assume would make a difference.

I was just trying to be a smartass... HAPPY FOURTH!
