How do I find out what my gear ratio is?
Divide one teeth count by the other. Now that you know how many teeth are on each gear, you can find the gear ratio relatively simply. Divide the driven gear teeth by the drive gear teeth. Depending on your assignment, you may write your answer as a decimal, a fraction, or in ratio form (i.e., x : y).
What should the drive axle ratio be on a truck?
Usually a whole number and decimal fraction, the drive-axle ratio is a comparison of the number of gear teeth on the ring gear of the rear axle and the pinion gear on the driveshaft. For example, a 4.11:1 ratio means there are 4.11 teeth on the axle’s ring gear for each tooth on the driveshaft’s pinion gear.
What should the gear ratio be in a medium duty truck?
In medium-duty trucks, gear ratios range from as low as 2.69:1 to as high as 7.17:1, depending on the truck class, make and model, and rear-axle capacity.
What is the gear ratio for a 15 tooth driver?
The ratio between the rotations of the 15-tooth driver gear and the 45-tooth driven gear is 3 to 1. That is, the gear ratio is 3 to 1. Using the colon notation, the gear ratio is 3:1. The order of the two numbers in a ratio is very important. In this case, the ratio of the 15-tooth driver gear and the 45-tooth driven gear is 3:1.

What should the rear gear ratio be on a Dodge Ram?
Crawl under your truck and look for a tag stuck on the bottom of the drivers side rear axle tube. The 2500/3500 come with either a 3.73 or 4.10 ratio. @PullYa, @JB1 If I put 37’s on mine after the 4” lift would you recommend a 4.88.
