ARB probably would only need minor changes to their current bumper offerings for the global rig given the US spec version may have slightly different brackets etc however thats a whole lot easier than building a ground up new bumper template for the US spec truck. However following the payload thread I could see lots of value about really being cautious about weight on aftermarket gear being added to the midsized trucks. Weight always seems to be the driving factor guys decide to sell and go to a larger rig or back track and simplify things some to shed weight.
