Raptor starter clutch
Go with the one way from L&L Extreme.
Then you will get an original from the person who designed it.
My freinds L&A failed and when he finally got a hold of someone to warranty it, it failed again.
I told him my L&L has been great, so he put one in and hasn't had a problem since.
If I had to do it again I would make sure it was from L&L Extreme.
