Whatever dude mine may not be as pretty as yours is but its far thicker. Mine didn't crack on my first trip in 4lo or any attempt yet. It hasn't bent, flexed, cracked, or moved one bit. It may need a gusset but just because its underneath doesn't mean it won't last. I can jack the truck up by that piece of steel, and if the axle exerts those kinds of forces on it then I should also be worried about it driving itself right out of the factory mounting locations. If the bracket does not last, I'll come back to this thread and apologize to you, but I'm confident I won't be doing that.
