Should have a read in this thread...... if you don't believe me as I know my springs on my Sahara Unlimited with tow package were a heavier spring!

so i have an 07 x 6 spd that i bought used. it has the hitch receiver so is it safe to assume that i have 3.73 gears? i have not looked to see if i have the wiring harness.

 

If the hitch is ***factory*** installed, you will have 4.10 gears on an 07. It is best to check by spinning wheels and counting driveshaft revolutions.

 

its true..my 08 has upgraded heavy duty coil springs that came with my tow package.Also 3.73's.

 

So I have a 2010 unl sport with factory tow package. So do I have heavier springs? :( would be nice. Wife and I are going to Tulsa tomorrow to pick up our new pop-up camper. While it's well under the tow rating on my jk, still would be nice to have the heavier springs ya know.
