Most of these Moose bumpers are made out of Aluminum,so they remain light. They are hinged on a half inch bolt on each side. Strong???
They may stand up to a deer hit but in my opinion they are there for looks. Beauty is in the eye of the beholder,because I think they even look dumb.
I went to work for a company and the truck they gave me had one of those things on it and it was a huge pain in the --- when you wanted to lift the hood. First you had to let that thing down and then put it back up after, and oh did I mention the rattling that drove me to cut the thing off.
