*7 Spline, 7 Tooth, 3" Pitch drivers are for the driveshafts on the Matryx sleds that came with the 2.75 track*
The above drivers are not replacements they are conversion drivers so those models of sleds can run different tracks
These drivers have anti ratchet points as well as involute Points. We call these our M series 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. These require your suspension rails to be trimmed and an anti stab kit installed. If you have a Polaris and your driveshaft is prior to the Aluminum Hex or Steel Splined shaft please refer to our Hex Shaft Drivers. 2022 Polaris Series 8 (3.5 pitch, 2.75 paddle) do not have 4 rows of bumps in between the rails. This style driver will NOT work with the 2022 Series 8 Track. Please refer to our T3 style anti ratchet drivers for 2022 Series 8 track.
