Late model Chevrolet S-10/GMC Jimmy light trucks were equipped with the 7.5 inch 10-bolt live axel. The common gear ration for this application is 3.42. If it was equipped with this ratio the ring gear would have 41-teeth and pinion 12.
41 teeth on the ring gear, 10 on the pinion gear.

41 and 11
The Mitsubishi 4G54 engine uses a flywheel with a ring gear that has 131 teeth. This ring gear is essential for the starter motor to engage and crank the engine during starting.
That is a 4:10 gear ratio. Just divide the number of teeth on ring gear into the number of teeth on the pinion gear and then round it off and that will be the gear ratio.
ratio is 3.73
The best way is to count the teeth on the ring gear and divide by the number of teeth on the pinion gear. Or you can count the number of turns of the pinion it takes to get one full turn of the ring gear. For example, if we divide a ring gear with 41 teeth by a pinion gear with 10 teeth we find that the gear ratio is 4.10:1 (41/10 = 4.10).
2.733333333333333333:1 ratio
The # of teeth on the ring gear and the pinion gear. There is always more teeth on the ring gear then the pinion gear. And the way you determine the gear ratio is devide the # of teeth that's on the pinion gear into the # of teeth that's on the ring gear and that will be the gear ratio. The 4 gears that are the same size and run together is called the spider gears. Do not count those gears they have nothing to do with the gear RATIO.
