Any part CAN fail. But, proper application, and proper installation, will reduce the risk of failure drastically. If someone bolts a rocker meant for a flat tappet with up to 300# spring pressure on a head with 500# springs and a solid roller, doesn't make the geometry right, and doesn't prelube, among other things, it is probably going to fail. They have no reason to blame the parts, but they do anyway. After all, the parts can't defend themselves.

I've used the stainless rockers on a 500+ hp big block without failure. I have not used the aluminum rockers, but I have a customer supplied, small block set in the shop now for a street/strip build. We'll see how they hold up.
