The P-22 flaw is that the outer sheave is constantly slamming against the clutch bolt head when the sled is in operation. Add in the vibration & the force of holding the clutch on it is a lot to ask of a single bolt. The Carbonsled sheave connector eliminates the stress the outer sheave puts on the clutch bolt. Adding this ARP clutch bolt will help I imagine but still would not trust it by itself to do all the work.
