Yes, the snap up is bent slightly outward, and evenly across, just below the sides where it hinges.

WOW.

I'm thinking that you may be really lucky you were using the older snap ups. I suspect that if there was enough force at the face of the frame to bend the snap up there, that there's a good chance the frame would have bent if you were using the heavy duty ones, since they would most likely not bend there.

Did you put a straight edge on the frame where the snap up mounts?

IMHO the 1200lb and up bars need the HD bracket. Also, not sure that the HD ones would have done any frame damage. In fact might have prevented it. Looking at the brackets, what happens is that w/o the extra support gussett the HD bracket have, if you get much doutward force from the chain, it will cause the std bracket to bend on the outside surface. that then trys to pull the inside towards the frame as it moves in and up, causing the bolt to dig into the frame.

On the HD brackets, the gussett supports the weak point that tries to bend outward from downward/outward cam forces. And also support the "U" section at the top from deflecting.

BTW, if the OP has the new style cam setup, are you sure you positioned the chain bracket to cam arm correctly?? any chance the bend at the top faces outward rather than inward??? If so, that may be part of the cause of the failure. If the bracket bend faces outward, then the chain is not pulling straight down on the bracket, it is pulling at an angle outward putting lots of force on the snap up bracket in a manner it isn't designed to see.
If it's the old style, any chance that the bar is hitting the cam?? again that can cause some bad forces on the cam arm and snap up bracket.

OP if you can post a picture of the bent bracket it can tell a lot about what may have happened.
