Rubicon

I recently purchased a 2006 GT Convertible with an automatic and the original owner left the window sticker in the glove box. I cannot find the axle ratio on that. Is there another easy way to figure out what axle ratio I have?

There should be a tag on the rear differential that lists the gear.

Unless you have reason to think the axle ratio was changed after the car left the factory, check the label on the door jamb, assuming the label is still there. I don't have '06 information, but I am not aware of changes in coding between '06 and the '07 information I have. CG is 3.31 with limited slip.

CD on the door sticker is a 3:55 I know. The sticker on the differential itself is most likely still there as well.

All Autos came with 3:31 standard

Only the Manuals had the option of upgrading to 3:55

OK, I looked on the door jamb, CG is the axle code

I was wanting to switch to 4.10 gears, I have to research and see if I need a new carrier or just maybe only go to a 3.73 I will see if the AM chat team is available to help
