33" tires with 3.07 gears

So I have ordered my lift, sye, and driveshaft and am going to buy my tires/wheels later this week. When changing the fluid I found my axle to have 3.07 gears. Is it going to suck that bad on 33" tires? I plan to get regeared eventually but that could be 6 months to a year before I do.

Obviously it won't drive and feel the same as with the 30" tires, but is it even going to be possible to drive on the streets/highways/trails with this setup for now?

I'm running 32's with 3.07's and an auto. It isn't terribly bad. Around town and on the freeways in the Phoenix area is does just fine and will keep up at 65mph traffic. Head up the mountains to Payson is another story.

Where its going to get you is freeway driving, mountain driving and low range. I have 33's and 3.73's and do OK on the freeway but I have to down shift for a steep overpass's. I lose 5th gear completely in the mountains and 1st gear in low range is nowhere near low enough.

with an auto tranny and the torque converter it will be ok for a while. I had 32s and 3.07 gears for 1.5 years and that was fine.

it works, you just use 4 low more and burn through more gas. don't be afraid of the skinny pedal and don't think about rocks at all and you'll do fine.

Well I have a 5 speed tranny. I am just wondering if I will still be able to run some trails with it. I don't plan on much highway driving. Just around town and trail runs. I know I won't be able to really "crawl" over much but just wondering how it will be off road.

Offroad should be ok. Won't be great, but it works.

TeeJAY: Now I like your idea, but don't want my D35 to suffer

I eventually plan to either swap out to a D44 or 8.8 with 4.10 gears. (Not anytime soon though).

Thanks guys for all the answers.

thats why you stay off rocks. You won't break a D35 on sand or in mud with 33's no matter how hard you try, they break because they catch traction and they dont do that with a loose or sloppy surface.

Don't ever let it hop. in all honesty though, I wheel hopped a d35 on dry pavement being stupid and broke a u-joint instead of a shaft. and if it comes down to it I'm sure we can rally our piles of junk and find a shaft for you if you need it.

jump under it. look at the rear diff. metal plug d44 rubber d35. gears will be on the tag. If tag is gone mark tires and drive shaft with chaulk and then turn rear tire by hand and count the revs of the driveshaft for one turn of tire.

right almost in the middle of the diff. It is the fill plug. If you jump under the gas tank it is clear as day

X2 on 4points comment.. I had 3:73 w/ 33" 12.50s and had to down-shift quite a bit.. Now, I have 4:56s w/ lockers and hate myself not doing it before any other modification.. She is a new Jeep!
3:73s are annoying; but 3:07s will be quite a bit of work.

no way if ure running 33" you need at least 4:10 but that's still not to factory. 4:56. i can climb anything and no problems on the highway.
