Yamaha Anti-Ratchet Drivers

These drivers have anti-ratchet points as well as involute Points. We call these our Mseries drivers as the anti-ratchet points run in the clipped track windows and the involute bumps drive off of the four rows of rubber track bumps found in between the track windows. These are sold individually, you will need to two per snowmobile. If you have a Yamaha and your driveshaft is prior to the 1.75 Procross shaft please refer to our Hex Shaft Drivers.
