Default 4.10 gears ??

Hey guys, I am a previous Jeep owner and now have started to look for a JK unlimited. I have my mind made up on a 6 speed and 4.10 gears.
My question is... is there any year,option, or package of JK that will have 4.10 gears from the factory besides the Rubicon package. I'd like the 4.10 gear set, but don't necessarily need the bells and whistles that a rubicon has. I have searched for a couple days and haven't sbeen able to find the answer. I know someone on here has to know.....
Thanks in advance for any answers and/or thoughts.

I think alot of unlimited came with 4.10's,, but honestly the 4.10's arn't low enough for the week motor. You will want to regear no matter what it came with from the factory.

What he said, 07 was the only year you could order 4:10's in a non-rubi from the factory.

Are you looking to buy new or used?

Last I heard, 4.10s are no longer an option for non-rubicon models.

Used is an entirely different story.

My 07 was ordered from the factory, half doors, 4.10s, bare bones, power nothing, X 2 door. Love it. Got lucky I guess.

Was looking to buy used, but did not want to buy an '07. I don't like buying the "first" model year after a huge change. Plus, most '07's have fairly high milage. Looking to put 33's maybe 35's on it after a lift. Did not want the added expense of regearing if I did not have to. Looking at the gear chart, I could 'get away' with running 33's with a manual and 4.10's
Thanks for the help guys....great forum!!

How's your Jeep run with tha 33's?? Do you feel that you have adequite power while still being able to cruise down the highway in 6th gear??

In the gearing charts, did you notice that manuals run over 500rpm higher than auto's, given the same gear/tire combo?

You could 'get away' with running 37's on a manual with 4.10's. You should have no issues at all with 3.73's and 33's.

I'd like to stay in the green...'acceptable gear for tire size, good daily driver'. Looks like with 4.10's and 33's are the size to have. Maybe 35's
Am I reading that wrong??
