Snowmobile driver diameter specifications

Changing driver size will also effect over-all gear ratio. For example when changing from a 2.52” 9 tooth driver to a 2.52” 8 tooth driver. You would multiply your 9 tooth ratio by 1.13.

Example: 20/40 gears with 9 tooth drivers would be 2.00 to 1. When switching to 8 tooth drivers with the same gear set the new ratio would be 2.26 to 1. (2.00 x 1.13= 2.26)

Note: the 1.13 multiplier only applies to 2.52” pitch drivers. Although the 2.86” is fairly close to the 2.52" and could be used for a 2.86" driver to get a general idea of ratio change.
