STEP 19: - Speedometer Calibration Data
Proper calibration of the speedometer will greatly depend on what changes have been
made to the axle gear ratio and tire size. There are some combinations that will not
require calibration changes (refer to the chart below) and are shown in the color gray.
The other data reflects what your speedometer percentage of error will be if the
speedometer is not recalibrated. If your vehicle requires recalibration a converter box can
be purchase. (Not Available from Omix-Ada – Rugged Ridge).
