okay thanks for clearing it up, That also brings up another thing that I considered. Selling the 33's and going to 35's now since they are still new and that would counter a big chunk of the upgrade cost to 35's. So many options, but if winch and bumper looks best I will do that.
If you go 35's and you have a 6 speed and 3.21's you will HATE rock crawling and your clutch will hate you even more. I speak from first hand experience here.
Get a lunchbox for the front (Aussie, Spartan), change out the ball joints and put a small lift on it, keep the 33's and you will have tons of fun. We wheel with a girl that runs 31's on her sport and no lift and she rocks that thing. You put a locker in the front and you will be VERY suprised at what you can do and the fun that can be had.
I'm telling you if you wheel at all (other than muddin') you will not like that JK once you throw 35's on it and run those gears...the only other option would be to look for a used Rubi x-fer case (good luck w/that).
Here a video of me wheeling on 35's and the gears you have....not pretty! Starts about 1/2...Gecko Jeep.
