I regeared my old 4 cylinder TJ to 4:88 and ran 33s just fine. With yours being a 5 speed I will say if you hit a steep bridge you'll probably have to downshift on occassion, I know I did. I also pulled the throttle body off of a 4.0 TJ and replaced the one on my 2.5, it gave the Jeep a little better throttle response.
