regear

hey guys, just got my new jeep. 02 tj with a 318 v8 swap. its got a 4 in susp and 3 in body running 35 bfgs. it has 4.88 gears and im thinking it might be a little over kill. what do you all think? i was thinking of going to like 4.11, just for a mpg but if it wont help much i aint to worried. thanks

with a 318 swap you will need to upgrade the rear axle to a Ford 8.8 or a Dana 44 rear. I'd got with the 4:1O's going lower will weaking the gears.

37's should be 4:88, 35's - 4:56, 33's - 4:11 to 4:27 will keep you near the stock gearing. but overkill is great too. I'd say forget the MPG.. larger engine, lifting it, large tires.... You've greatly increased its wind drag and you've ruined any chance for reasonable gas mileage.. 14 to 15 in town and 16 to 17 on the interstate is to be expected... but then again it's only my opinion..

What transmission was put in with the v8? That does affect what the best axle gearing would be.

I don't know what fits the 318 V8. It would really depend on the transmission you have and if Jeep offered a Part-time transfer case in that year. I'm sure others have looked into this. You might be able to Google it. Probably any transfer case can be had for less than $100. You might also run into drive shaft length issues as well. Maybe find a donor Jeep with the setup you want.
