i did a search and didn't come up with much, i know that anyone can throw the 30 inch tire and wheel package on any TJ but he ones that came from the factory with them, did they have any different gearing? thanks!
I think they did. In '97 it was only available with the 3.55 gearing, but in '98 they did away with the 3.55's and went to 3.73's. Not sure if it was mandatory, but I think it was, so you should have 3.73's.
