Google much?

No. 3.73's if automatic. Only Rubicons came with 4.10's.

:beer:

Edit: obviously I'm wrong :laughing:

For 2007, Rubicons and all automatics got 4.10 gears (tow package or not). The only other ratio available was the 3.21 on the 6-speed. 2008 and up only the Rubicon got the 4.10 ratio, 3.73's came on board for the other models.

Lift one rear tire from the ground,transmission in neutral,no e-brake,put a mark on the lifted tire and one on the drive shaft,spin the shaft,if you count 4
and few degrees and your tire spin once you'll have 4,10;if you count 3-3/4
and the tire spin once you'll have 3.73.good luck!

Close, but if you when using this method you need to double the tire rotations if you have an open diff. If you have a limited slip or a locker then the above method works with both rear wheels off the ground.

So, jack one tire off the ground, block your front tire so it doesn't roll away, tranny in nuetral, ebrake released, mark the tire and the driveshaft. Now turn the tire slowly for TWO full rotations and watch the drive shaft. However many time your ds spins is the gear ratio you have.

just remember;
2 full tire rotations, appx. 3 1/4 ds turns = 3.21
appx. 3 3/4 ds turns = 3.73
a little over 4 ds turns = 4.10

I think you should also be able to get your build sheet from Chrysler, which should give all the info on your rig.

Those are good tips, but isn't it easier to just get a build sheet from Jeep?

well guess what

:shaking:

I did Google and found conflicting answers. So I called Jeep and my particular Jeep came with the 4.10 gearing. It turns out some Saharas came standard not just you Rubies PROs . Thank you all for the Info. I know I can always count you guys.

Thanks

I got the build sheet on my 2007 sahara, 4.10 gears limited slip rear( I forget what jeep call it) and mines a 6 speed. The build sheet was very informative.

I thought is was an option.


I got 07 unlimited, pretty sure it has 3.73's
Then its a weird late model 07. The only 2 available ratios in 07 were 4.10 and 3.21


My 2 door auto came with 4.10s and an auto, no tracloc and no tow package. 4.10s were a 50 dollar option...

He's probably got 4.10's. 2007 was a long time ago and people have forgotten that there was a 4.10 ratio available on other than Rubicon models.

It's not that big of a deal. People just need to stop jumping the gun and posting stuff as fact when they're wrong.

2007's had either 3.21's or 4.10's from the factory.

3.73's were introduced in 2008 as a "fuel saving" effort... haha
