Actually, if you drill a hole in the center of the Bud's bumper, put an aluminum stand-off on the bumper and then thread a ball end into the top of the diffcase, where there's already a nice convenient hole, you'll have a bumper that doesn't deform, and doesn't break like the RPM bumper. That whole set-up also weighs less than the RPM bumper, and I'm certain the Bud's bumper provides better protection for the front-end, my father has tried both and the RPM bumper is just quite simply not as good.
