I recently picked up a 2014 Ram 1500 HEMI. Per the window sticker, 3.21 is standard and 3.55 comes with the 26Y package. On the axle, I found a sticker that says, among other things, 3.21.

Does this mean I've got a 3.21 axle? Or is there any chance they swap out the gears separately after the fact? Am I going to have any way of knowing which gears I've got?
