Most people use the RK Tek adjustable helix and are pretty happy with it. It allows user control and allows you to dial in your sled depending on the mods you have. As for the puller for the drive, pretty sure the Arctic Cat only makes one now for all their primaries.

2010+ M8 uses a different puller than 2009-. The HO puller is the same as a M1000.

I really haven't had problems with either Rock or the high temp but you should also order new helix bolts or find some better ones to put in. They are not very strong and the stampings are too shallow.

x2 and if you are really unlucky they will break when you are trying to take them out!

I haven't had to much luck with the rock rollers,I seem to break one every ride.
As they are a pain in the azz I tapped and added bolts to hold the rollers.
It takes around two minutes to replace on the mountain.

As for the torx screws holding shives together make sure you heat them up or they will break.
They use red lock tight on them so don't forget to lock tight them on replacement.
I take clutches off of Cats all the time with water.Lay sled on side then pour water into the bolt hole then Teflon tape the clutch bolt a bit thick but don't over do it then tighten it up and the clutch will just pop off.
If it don't happen the first time it always pops the second time.

This picture of pin replacement bolt is 1 7/8 long and is stainless steel.
Go check out you local bolt supply and you can get a torx or Allen head stainless bolt then machine bolt head smaller diameter then rethread with a smaller die to keep the pin the same diameter....that make sense?! Lol
I had a bunch machined a few years ago but am going to need to get some more soon for latest builds.

I see that if you get the Cutler torsional clutch kit it comes complete with roller pin bolt conversion.
