Thanks for the info. I'm right now set on a 4.0L, i wanna run 33's, nothing more than a 4" lift, and i'm thinking a 4 cylinder would just struggle with it unless as you said, i get it regeared. Which, is like so many other things, something i don't know enough about to just go and get done. I have a best friend with a '95 Wrangler thats got a 4 cylinder, 4" rough country lift and 29" tires, he's scared to put any size bigger, and....it looks kinda puny with such small tires. As far as usage goes, i just wanna do some conservative trail riding, nothing to major because i want it to stay driveable for an everyday trip to town, not always gettin something fixed. What does it cost to have a 4 cylinder regeared?
