After my lift and new 35" tires, I've noticed a big drop in MPG.
So I'm doing some research on the Superchips Flashpaq before I buy it. I've read it asks you your gear ratio. I have no idea!
I did not buy my jk from a dealer.

2007 Jeep Sahara JK Unlimited 4x4 Automatic

Help!

 

I bet running your VIN would tell you how it came equipped (assuming they weren't changed. If you have the towing package from the factory, then you have 4.10 gears (it's what I have).

 

Tow package? I think 4.10 if you do

 

'07 unlimited, probably 3.73, possibly 4.10. Doesn't matter though. The computer knows what you have now. The only time you will need to change that is if/when you re-gear. And I am guessing that if you are paying over a grand for new gears, you will know what they are to program them in...

 

Ok real dumb question, if my Jeep has the tow package then it would have a hitch right?

 

Unless it was removed.

 

Best way to know for sure is call the dealer and ask for a build sheet when they run your vin. They should be able to tell you instantly.

 

I have an '08 Sahara with the tow package, and it is running stock with 3.73s. Send your vin number to Jeep (you can do this directly from Jeep customer support online) and ask them for the build sheet on your Jeep. it is free and they give you all the information you will need on your stock set up. Here is the link, just click on the send an email link on the upper right. You should get an email reply within a couple days, I got mine in about 5 hours. Hope this helps.
