Hello,

I'm looking at buying a 09 sahara 2dr and I would like to know if there is any way of telling what gears come in the saharas? It doesnt have the tow hitch if that matters? 3.21 or 3.73?

09 Sahara 2 dr Auto

 

3.73 if it's an auto. Or at least the 2010 and 2011's

Edit to add - I think there's a marking on the read diff cover.

 

My 2010 Sahara was 3.73 auto with tow package.

 

My 07 Sahara was 3.73 stock or 4.10 with the Towing Package.

 

The auto Sahara would include 3.73 gears. (Unless a previous owner re-geared it.)

I have never found any markings or tag on a JK diff indicating the gear ratio.

 

I will add that my 2011 is the 2.73 with auto and tow package. Not sure what years might include the 4.10 with tow but not the case on the 2011 saharas

 

Yep .... 3.73 .... iPad is not ideal for typing

 

Well I guess that means that it has 3.21 gears since it has no tow package?

 

Nah, only 6-speeds come stock with the 3.21s these days; some early build ('06 & some '07s) JK autos came with the 3.21s but they were such dogs to drive due to the high OD gearing that 3.73 has been the standard ratio (except for Rubis & tow-pack equipped vehicles) offered with the auto box since '08 anyway as far as I know. For an automatic JK, & particularly the heavier 4-door Unlimited you'd want to be looking at optioning 4.10s if you were buying one new.

 

So, you didn't see the top half of post #5?
Auto came with 3.73 in '09.

The autos in '07 came with 4.10 gears. I wasn't aware they ever tried 3.21 with the auto.
