The spider gears will double the wheel speed so your 3 3/4 turns of the driveshaft will actually be approximately a 7.50:1 ring and pinion ratio. To get an accurate count of driveshaft revolutions it would be necessary to roll the truck forward in a straight line and count the driveshaft turns for one turn of the rear wheels..
