Yes. I run the HD hitch bumper on my 165 g4 (dealer ordered and installed it by mistake rather than the standard HD bumper that's upturned).
Works just fine. It's very bomber. Towed a buddy out of the forest just last week with it! The tow bumper saved me $150 over the standard HD version (thanks dealer).
I imagine you could flip the bumper, but even so, it's not much of an upturn/downturn compared to other bumpers. Note: the removable snow flap does not work with the tow bumper, at least not to easily/quickly engage the removable portion because the turn knobs won't clear the HD tow bumper.
