4.88\'s in 4 banger TJ.

The lift and change in tire's to 33's has left my poor little TJ struggling. I am planning a gear swap soon and have seen a lot of discussion on here about them. I guess my question is, is anyone running 4.88's behind their 4 banger. I don't want to go so low that I can't cruise comfortably at highway speeds, seeing that I spend a lot more time on the highway than the trail. Would 4.56's be enough or would I still not be able to use 5th gear. Any suggestions would be appreciated.

Re: 4.88\'s in 4 banger TJ.

I have a 4 cyl YJ, and the stock ratio is 4.1 with the manual trans. I am not sure what the TJ stock is, I am guessing its the same. I am also assuming (for the sake of my point) that your Jeep came from the factory with 27inch tires. So from the factory you had 4.1 with 27 inch tires. With 4.88 and 33 inch tires your RPMs will be just about the same as stock. Give or take 200RPMs. So if you liked the rpm feel of the stock setup then go with the 4.88s
