how long?

You can get a max torque long keyed clutch and adapter plug if you are stuck with a small shaft.

If you are talking about the other shaft,, I think there's an adapter for that to!

Some clutches work with short shafts.
Some need longer shafts to bolt on to, like the racing clutches.

Bottom line is:
If your making lots of power, you need a long shaft or you could shear the keyway.:thumbdown:

I have seen it happen.:doah:
