Assuming a 3' wide 12" high bump with 1.5' of ramp up, at 60mph (88 feet per second) the suspension has 0.017 seconds to absorb the 6" of uptravel and then transfer the other 6" to the truck. Someone did the numbers on it, but that is a lot of force to absorb in a hurry. Aaron Z

I wouldn't do what they were doing with their trucks either but don't think the frame should be the weak link. The hole in the frame and it not being boxed where it bent is a big issue.
