I've never liked the Westin Bull Bar or Ultimate Bull bar. It just make's the front end look so low. I think think they look great on lifted trucks though.
I would really have to see one on a 4R before I could pass judgement on how it look's on them.
I really like the T&H euro bar , look's factory and would''nt mind getting one of those , not sure if I should go stainless or black and have it painted to match the truck or the dark silver color of my tube step's and roof rack. I can get it painted for free so it would'nt cost anything more.
