Default Comp pro mag poly lock failure

Anyone had any issues with the poly locks with the promag rockers? I had one basically come off/break on a nitrous pull on the street...... Made some pretty scary noise with the exhaust valve closed. My buddy was helping me out and went to tighten the poly lock and it just snapped right off.

NO. I haven't really had any issues at all. Where did it break at?

There are a few lt1 guys who have had promag failures. i know they are two differently designed rockers, but you should call comp. They told one guy that those rockers are not designed for track use or high rpm(WTF?). So they upgraded him to the high tech stainless units for free. To bad the bottom end got trashed...
