3.07 is for economy, not performance. With tires bigger than 27-28", performance is going to be abysmal. Yes, 3.07 is too high of a ratio for a Jeep that runs bigger tires and goes offroad.

When you have a choice, buy American.

i have 3:07 with 35's and it sucks royal ass. if anyone is interested in a rock river arms AR15 let me know. I'm selling it to get new gears. oh yeah, its damn near impossible to find a replacement axle too.
