I think you're talking about the shelf on the lift block? There's nothing on the axle. I could see that being a cool design but, to "design a weakness" into that shelf wouldn't neccessarily be the most efficient considering it takes hits on more occasions than the hard hits to the frame. So in turn, it could bend over time with lesser impact. The frame being the part that bends does sound extreme but, one of the whole points of this is that it shouldn't be taken to that limit or put in that position in the first place. When it is, it needs to get past the bumpstop first and then to the frame.....and then you can drive out and not be stranded in the middle of nowhere.
