I think the second "fail safe" bearing is an interesting idea, but the way this thing looks with hex cap screws and rivets is completely lost on me. Why, of all things, would the flange have rivets in it? Is it supposed to look cool, like the fake 2 piece wheels? LOL

I have the LN IMS "upgrade" in my engine, which contains 3 bearings, but unfortunately cannot be done without sending the whole shaft to them, though I do love the idea that it's not one single point of potential failure.

I think it's wise to consider this thing a preventative maintenance item, to be replaced at every clutch job.

Now, I'm also completely lost how they claim they have "engineered" a prescribed amount of "slip" into the interface between primary and secondary bearing. Sure, you get far enough and you'll throw cam timing faults, but how is the bearing supposed to only "slip" so far?
