I have a 21:48 stamped on gear set in one car, and 0.4375 is what I calculated it out to, not sure what that means. It is a matched set.

best way to determine gear ratio is count the teeth on the ring gear and count the teeth on the pinion devide ring gear by pinion

48/21=2.285... or 2.29:1 to get .4375 you have to do it backwards. What RPM are you running with this gear set?
