I've bee reading alot and have learned alot frorm the board about gear ratios...I think. I am still confused a bit, but I think i am getting it. Is this explanation correct?

1. If the gear number is larger (for example. 3.73 vs 3.08) 3.73 is a larger number, but the diamater of the gear is smaller than the 3.08, so the 3.73 takes more revolutions to turn the axle one time which equals high rpms at highway speeds, but more torque off the line?

Am I getting close or am i totally wrong.....Thanks .... Rick
