So, you want to know your crawl ratio. Or maybe you'd like to know what your crawl ratio would be if you upgrade. Select your transmission, transfer case and axle gear ratios in the calculator below and click on the Calculate button.

Formula : Transmission Ration * Transfer Case Ratio * Axle Ration = Crawl Ratio

What? You don't have the above transmission or transfer case or just want to try some other values? The calculator below computes the same equation but allows you to input different numbers. Input the ratios as decimal point values such as 3.73.
