Nope. The driveshaft would turn 3 3/4 times to one turn of the wheel. The ratio is 3.73 - 1 (almost 3.75 - 1). If you counted the teeth on the crown gear (the big one) and divided that number by the number of teeth on the pinion gear, you'd have your differential gear ratio of 3.73 - 1. Hope that helps.
