Well the point of the new bumber is being able to use it to push yourself up and over things. Using it as sort of a ramp. But I am wondering does this winch fit in the slot provided by an ARB bumper? And to answer your question, I have never heard of reinforcing a stock bumber. Currently, it would rip it off like nobody's business. But you could probably reinforce it. It probably won't be so pretty anymore though
