there are a couple of causes of this problem.
First, what bars are you using?? The 1500 and 1700lb trunnion bars come with the HD bracket, the others don't. IMHO the 1200lb bars should also have the HD bracket and from what I've heard, new 1200 and maybe even the 1000lb bars will have the HD bracket.
next, by far the most likely reason for the bars bending is that there is insufficient clearance between the cam arm and the bar. My guess is that from your description that is possibly the problem. While it may look like you have enough clearance, when the bar rides up on the cam in a turn it reduces clearance between the bar and cam arm. If it makes contact there is tremedous off axis force applied to the snap up bracket and it can easily bend down. To check, with the system set up do a slow sharp turn with someone watching and check clearance. If that is ok, then do a sharp backup and check clearance. if either is close or contacts, the solution is to increase the tilt on the head to drop the bars down. Even with clearance on level ground, and off camber up or down turn can result in interference, so make sure you have adequate clearance when level. the clearance issue is worst with the early dual cam with the flat chain bracket on the cam arm, much better with the new style with an angled chain bracket. Also, a top mount hitch on a 6" frame is more likely to have clearance issues than a bottom mount hitch. And the round bar is more likely to give interference than a trunnion hitch. With the top mount hitch on the trailer frame many folks, including myself use a 1" riser ball to gain clearance.
Another cause of the bending is with the new style the chain bracket MUST have the bend towards the frame, not away from it. If it bends outward, it is now applying an off axis outward force to the bracket rather than a vertical force and it can easily bend the snap up bracket. This isn't a problem with the old style since the chain bracket plate is flat.
And finally, once a bracket bends, it's toast. even if you straighten it out, it will easily bend at the same location again.
