Below are the DSM gear ratios. These are very useful to use in EVOscan or ECMlink to calculate the horsepower of your car.
Ensuring that you have the correct gear ratios between different parts of the drivetrain is cruise. It is important not to mix-match transfer cases, rear ends, etc. with the wrong combination of drivetrain parts.
