Id like to try that part along with the keyed hub on my car as I think it is a perfect compliment for the keyed hub we are installing. I disagree that that alone will fix the issue, as the bolt being loose is the affect, not the cause of the hub spinning. As soon as the hub spins and spits out the friction disc and wears the oil pump gear face, there is no longer any tension on the assembly, and then the bolt appears loosely torqued.

I know you guys have been working on this, but so have we on more powerful motors than any S55 currently. From my testing, I 100% Disagree with the thinking the bolt is the effect not the cause. There is no way to tell between the two once it happens. Did the bolt back out, and cause the failure, or do the crank spin on the hub, and cause the failure leaving the bolt loose. I believe its A for numerous reasons which I wont get into. If you want to try one of these, no problem. I have 25 coming, I will send you guys one. Just email me your address. [email protected]
