I have a Arctic Cat Roller secondary I want ot try on my 04 ProX 600. Engine and pipe are stock. Any one know what helix and spring to use?

cpc black/white, 50-42 dalton (same setup i'm running in my hyperlite cat style roller), should work nicely, may not be perfect, but should be close... you'll prolly be able to keep the stock weights and go to al/red or al/blue primary.... PERC won't work on this clutch...

In TEAM's translations, and by what comes stock on your Pro-X, you're probably going to want to end up with a 51-53 deg finish angle. The button secondary on an edge was using a 45/36 and went in to a 58-42.46 in a Team for the same application which is the same setup that equates to a 51 deg Cat roller w/ red-wht.

My question is when ever there's a conversion from a Cat roller to a Polaris, recommended finish angle is so much less than what is used on a comparable size Cat? And I don't mean anyone's personal recommendation as I've gotten the same thing from different manufacturer's.

ive got some expierence with cat rollers on polaris,assuming your primary is stock on a 600 i would try a 54/46 with a cat red white,middle hole,ive seen those conversion charts from team,seems like they always compare to cat straight helixs, and i dont know if i agree,i dont have much expierence with cat straight only multi.i know what you mean when you said cat seems to have higher finish angles,some of them seem to have a ton of weight too,usually thats because they have heavy springs in the secondary.i was running comparable clutching on my 700 pro with cat secondary to my f7 buds.
