king cobra's are junk, not because i've known anyone to have promblems with them (they do a good job) but because they end up slipping with low miles of them and or not much hp going through them, and they take a deranged pissed off ape to push them to the floor.. everyone called mine the "ground pounder"
spec stage 1 is much better clutch, the clutch i have is even better, but its a secret

i'll give you this much of a hint though, its made as a factory replacement clutch for 500hp and below honduh's
