Dodge / Jeep Speedometer Gears
Many tire makers build their tires differently, so a 35-inch tire from one company to another may vary as much as a full inch. The short shaft gears are for an electronic speedometer and the long shaft gears are for a cable driven speedometer. This is true most of the time, not always.
The index mark always goes straight down according to the tooth count.
