The bumper by itself? No. The factory bumper assembly isnt exactly light, even though its more than 1/2 plastic. My mopar bumper (a full width bumper) didnt weigh much more than the stock one. Maybe 10-15 lbs or so if that. Id take a guess and say the stubby by itself would weigh the same or maybe a touch less than the stock bumper.
