hello i want to know about the differential gear ratio

first : 3.46 vs 4.10 they mean the 3.46 is longer than the 4.10 ? or what?

second : how can i transfer the number of the ratio to the number of the teeth example: 3.46 = 11/38 ?? what is the method to convert ?


thnxs i wait your reply.

The ratio is the reduction is speed of the drive shaft relative to the rotation of the wheels. A lower ratio reduces torque amplification and results in a lower engine speed for a give road speed. A higher ratio has the opposite affect.
