Nah, for real though, they seem to be pretty heavy gauge steel. I just rarely ever see people running them with p-pads or anything like that. Not sure if it's just a style thing, or if it's because they're not strong enough.
They're heavier guage steel than the repop. junk that comes from J & P and they have a rib down the center which provides further stiffness, so yes. If your lady friend is REALLY burly, torch, bend and weld a narrow leaf spring in there for additional support.
