Do you know the gear ratio of your truck? Is the ratio right for your trucking operation?

Lets talk about rear end ratios. Most people get confused about what the numbers mean when you talk about gear ratios and how they affect the drivability and perceived performance of their vehicle. I believe almost all vehicles have a gear ratio of some sort, even a go-cart has a gear ratio of some sort.

So what is a gear ratio? According to North Carolina State University: "The Gear Ratio is defined as the input speed relative to the output speed.". Using simple numbers if you had a gear ratio of 1:2 or 1 to 2 , that would mean if the input speed is 100 revolutions per minute (RPM) (the 1 of the formula) the output speed will be 200 RPM (the 2 of the formula). The formula numbers can change to meet the needs of the vehicle in question.
