Re: 3.73 gears??? Need help
jack up the rear , mark the driveshaft
then mark the tire , spin the tire 1 revolution and count how many times the drive shaft makes a complete rev , that'll be your gear ratio
1 spin of the tires , 3 3/4 spins of the drive shaft would be about a 3.73 ,if it goes slightly over 4 spins you have 4.10's etc .....
