I like bull bars on some trucks (my Tundra for example has one) but i dont think they look right on these trucks. Just my opinion.
Also, are you anticipating using it for only looks? because u cant use a bull bar for anything other than looks. they are thin, flimsy and weak. but thats why i like em. A few crash reconstruction classes and you will agree with me. adding something big and huge that just transfers crash energy into the frame and cabin instead of letting the crumple zones and energy absorbing zones work they way they are designed is a bad idea.
now, the push bar like posted above? not sure why. maybe if you are a cop it might be something you could look right but really its gonna look just like u bought a used cop car/truck at an auction and it came with it. kinda cheapens the look of it IMO. makes it look...well..you know the people who buy ex cop cars...dope heads.
