The stock slip gear is 45 tooth and that is about the only toothed slip gear available at this time. Any Polaris HYVO gear will work. The slip gear is only necesary for Agressive SnoX racing and is not really necessary for anything else.
Much more important is the proper bearing in the bottom of the chaincase. When you pull your case apart look at the lower bearing, if you can see the roller balls of the bearing in a cage your have the correct bearing. Look at this picture,
IQ Chaincase The upper bearing is stock and the lower bearing is the "Self Alligning Bearing" This bearing will save your chaincase from sure distruction even if you are just trail riding the sled.
The Polaris Part # for the bearing is 3514462 (Bearing-205 Self Aligning).
Thanks tom that was the info i was lookin for .
what application for the gears i am going to try the 21 /43 combo
with the stock 76 pitch chain. sound ok .
I knew the bearing was wrong when i went to dealer for the chain case seal and bearings
but they wanted to argue about it . so i will change it
