The only choices for the '07 model year were 3.21 and 4.10. All the automatics came with 4.10.
If you bought it used, a previous owner could have re-geared it.
An easy way to tell what gears you have:
Chock a rear tire.
Jack a front tire off the ground.
Spin the tire by hand, exactly 2 revolutions while counting the drive shaft turns.
If the drive shaft turns only a tiny bit over 4 turns, you have 4.10 gears.

A rear locker and e-disconnect front sway bar were options for non-Rubicons for a few years, too.

Man would those be some nice features to have! So every 2007 auto has 4:10's or just the ones with towing packages?

I'm running 33's now and its never really felt sluggish to me.. Im just happy to hear that i wont be rolling 35's on 3.21's. I know its going to be sluggish. I bought a jeep. Not a camaro. And for goodness sakes look at the aerodynamics of the poor thing.. Haha but all in all i love it to death!
