Upgrade alternator
I'm going to upgrade my alternator to a bigger amp one. What year of zj am I asking for at the parts store and will I have to replacing the pulley also or does it have to have 6 rings or have 5. If it has 6 do I use the first 5 starting from the engine out or vise versa

I'm assuming you have a 97 from your username. You'll want the 136A alternator from a ZJ with a 5.2 (93-98). Keep the pulley you have now, it will be easier that way. I'm not sure if the pulleys are a different diameter or not on the ZJ but when I did my Durango alternator they were different.

Hi guys, after searching the forums, it seems that people have more questions than answers about the swap. Do any of you have a write up?
I have an 89 and would love to upgrade.
I don't mind a little grinding to FIT it in, but would prefer one that plugs in (or at least has minimal rewire).
