These are a super durable alternative to the "disc" style clutch, it will hit fairly hard and hold really well with less maintenance then typical disc set ups. It will also be much more tolerant to low speed on off engagements of the clutch common in back yard or trail riding.
It will engage about 3700 to 3900 rpm with the stock springs but can be tuned, these will use bully style drivers.
They can however loosen up around the driver/hub and create a "dinging" or bell sound while idling, if that doesn't bother you then this is a great all around clutch to use
