ARB is the only company I know of that crash tests their bumpers. They are designed to absorb impacts to avoid damaging the frame. A lot of aftermarket bumpers are super stout, but in an accident, what do u want to bend? The bumper? Or the frame? A buddy of mines wife crashed their 80 into another car. The ARB bent into the grill and fender. He bent the arb back, fixed the body damage, and the 80 is still used off-road. The arb looks like its been through an apocalypse, but he still uses it.
