Just wondering what gears my 4 door JKU come with?

 

Go to Jeep.com under Owners and create an account. The account creation process requests your VIN. Once you have that done you can get the build sheet under Learn & Use> Equipment. Your axle ratio will be under Standard Equipment but check Optional Equipment to see if the ratio was upgraded.

 

You can go to The dealer part desk with your vin # and get it too.

 

Sweet I will try that this AM! Thanks guys!

 

This is what I got

Next Gen. Dana 30 Solid Front Axle
Next Gen. Dana 44 HD Rear Axle
3.73 Rear Axle Ratio

Is this stuff any good?

 

That's great, I'm on my iPhone so I can't tell if your auto or stick but either way that's decent gears. The auto would like 4.10's more but 3.73 are a great start. What else did you learn from the sheet, trac lok, tow package etc?

 

I have an auto! Wish I had a stick, wife cant drive one.

I learned alot about my truck. Great advice on going to Jeep.com and signing up!!!

Would ythe 3.73's work with 35's wheels? I hear everyone like to have 4.10's in there rigg.

 

I am in same boat. 2008 auto and looking at some MB72's with 35 km2's. today is d-day for me to decide. Lol.

 

Wonder with 3.73 gears if that will strain the gears with 35" tires?

 

Don't know about it straining the gears, but you'll find the desire to re-gear will become overwhelming.
