I have a 2007 JK Sahara Unlimited with a manual transmission. I put the rough country 2.5" lift on and now am looking for some 35" tires. It is my daily driver that will probably never go offroad. Will I need to regear?

 

What gears do you have now? 3.73 or 3.21?
I have 3.73 with 35s and have not regeared. I have an auto and run with OD off. Get a programmer and run in 5th. 6th will pretty much be useless unless you regear.
Long story short: It's totally up to you, I personally don't mind running with the OD off.

 

Terribly noobish question incoming... how would one know their gear ratios?

 

Check your options list.. It will be on there..

 

With 35's, you will want at least 3.73. Also depends on if you plan on pulling a trailer or not, if so, you might want to consider 4.10s if running the 3.21. I have 33's with the standard tranny and a 2.5" lift and no probs with the 3.73s.

 

Found it. I have 3.73. Good to know... :P
