i think you'd be hard pressed to find something wtih the strength of an ARB bull bar. i believe they're capable of hitting an 150 pound object at highway speeds and not even noticing. (i've heard rumors of this being confirmed with kangaroos in the outback) it sucks that yours makes your jeep overheat. i'd keep looking into different ways to get that temp. down so you can keep your bull bar. i cant think of any alternatives off hand because i'd never considered anything else for my jeep, but you could try a google search for something. but if one makes it over heat, wont they all?
