I feel your pain. I just finished going through this myself. So far as I can tell, the ONLY aftermarket front bumper option/modification for the late model body style tracker, still offered, within the US, is the "westin" bull bar. I wanted a bumper for my 03 tracker but lack welding skills/the money needed to have somebody professionaly fabricate a bumper. I went with the westin bull bar (black) through SUMMIT RACING (great prices-fantastic customer service-quick shipping). I just mounted it last week and it looks great. They still make this for the tracker although the company had to make another production run for the mounting kit. I don't know how much longer this will still be made. Every other aftermarket bumper for the tracker in the US is out of production. I researched this thoroughly! Good luck....
