Gearing vs Tire size

I have a JK 2dr Rubi (auto)on its way with 4.10 gearing. I would like to run a 3" lift and 35's on it. Can the 4.10 handle the 35's or am I going to be faced with a sluggish vehicle and not be able to use overdrive, etc. I don't really want to regear right now. Anybody running 35's on their Jk, I would greatly appreciate your input. TJ owners also chime in. Thanks!

i agree with second tj u should be fine. but u still will notice lack in performance that comes iwth putting bigger tires on but if u want to go back to stock performance then regear will be a must but if ur fine with the small bit of a loss u will have then ur good

I can live with a small bit. I have read threads about loosing overdrive, not being able to pass on the freeway, etc. I am sure some of those threads weren't 4.10's though.

35's I believe need 4.56's

I had a 99 TJ with 64,000 miles and I ran 35's BFG Muds, I would take 4.56's anyday. It was a manual and a blast to drive. That is just my 2 cents

You're still above the 3.21 ratio that the X and Sahara 6-speeds come with. A little more weight, and a little more rolling resistance, but I think you'll be OK.

What does it cost to regear and when do you think the JK will have gears available. I am sure companies are working on these as we speak. Anybody know?
