thanks

anyone?

If that is stamped into the helix, it's not a factory Ski-Doo one. I will bet it's a Goodwin Performance aftermarket helix, hence the "GP ###"

Yes it is a goodwin but what is it?

heavyD try to call them and tell them your working on a clutch setup and you would like to know what the helix is so you dont buy the same one you have now.I did this and they told me.hope this helps
