Gear ratio

Can anyone confirm this is indeed a 4.10 ratio gear set? Doesn't seem to be stamped like stock set that I'm used to at least but maybe the aftermarket does it different. It's the only numbers I can see decoding to that.

Re: Gear ratio

Count the number of teeth on the ring gear. Count the number of teeth on the pinion gear. Divide the teeth count of the ring gear by the teeth count of the pinion gear, that's your gear ratio.
