a set of those are almost a must for a hyper 7, the standard knuckles are the biggest weak point as where the kingpin screws in the hole tends to open up leading to the screw falling out (usually in the last minute of a heat)
once you fit the cnc knuckles you dont have to worry about it ever again

CNC knuckles are definately on my list of bits to replace, thanks!
