ok...sorry in advance...but i need a professional opinion...i have a tera flex leveling kit on a 07 Unlimited with 4.10s...can i run a 34.9 or a 34.7 tire without re gearing...or should i go down to a 33...thanks in advance..

 

You are already running a 33'' tire. I would run a 35 with the 4:10 gears if you don't need power for mountain passes on the highway. I will be running 4.88's because of the mountain passes I travel on when I upgrade to 35''s.

 

If you've only got the leveling kit and aren't running flat fenders, then you probably can't fit a 35" tire under there. The TF Leveling kit is for a 33"-34" tire setup. If you want to bump up your tire size (which - to answer your original question - lots of people seem to be ok with keeping the 4.10 gearing on) to 35's, then you might want to look into either going with either flat/trimmed fenders, or else a 2.5" lift kit.

 

Thanks for the advice guys......think I'll go 35 ...want to trim my finders anyway.

 

quick question merlin..gonna trim my finders as ive said...but would adding a 1 nch body lift help at all with the 35's......body lift is cheeper than new lift...thanks

 

you can probably get a used 2.5"BB for cheaper then a body lift.
u'll still nee to cut the fenders though... i rub my fenders pretty badly and i'm running 33s.

 

can u still run TF leveling kit with 2.5 BB ( i know, stupid newby question)....want 34 - 35 and dont wanna do away with leveling kit...

 

Not sure. I've never messed with body lifts myself, but it seems like it might work. But the fender trim is free, so I'd try that one first, and if you still rub - since you were going to do that anyway, then I'd go from there with the other options.

Or...you could always pick up a used 2.5" BB here on the forum, and then sell your Leveling Kit to offset the cost. That would be an inexpensive win-win situation as well!
