Rear bumper for hitch- crash rated

[VX KAT]

Found this cool lookin' do-hicky when looking for a bumperette for my new "tone-style hitch" I got from T4B.
~Patented compression system
~Capability: Stops 1 ton @ 4.34 mph (without you feeling anything) -
~Withstands 15-20 mph impacts.....

I just want something I can scrape the p@*p out of the bottom to prevent rippin' up my lower rear cladding and gas tank plate going down some of my favorite Moab trails......don't think the compression system would help much in that scenario....any thoughts?? What does Kodiak have? Anybody recall the brand?
