Just wondering what rear end gears I have. 2011 QC sport fully loaded. Doesn't say on the window sticker that came on the truck when bought new.

Jack up your truck. Rotate rear tire 1 time around & count how many times the driveshaft spins. 3.5 times 3:55, just over 4 times 4:10

If it is an open rear diff, then only jack up 1 side, otherwise, you will get 1/2 of the number.

I just got my VIN report back on my wife's brand new 2014 1500 Laramie. It has DMCS 3.21 Rear Axle Ratio.

If its a '14 with 8 speed, most generally they are 3.21's, '13's and older, 3.55's and some with 3.92's.
