I have a 97 jeep wrangler with a 4 cylinder that i just put a 4 inch lift and 33 inch Swampers on. It has 4.10 gears right now, but with the new big tires i dont know if the old gears would be enough. And with the anemic engine that the car has im doubly worried. Should i upgrade to 4.56, or even 4.88 gears? Or am i worrying for nothing?
