How do you know? I assume he’s running an angled relocation bracket, but what trackbar? Nothing really works except the Currie, that I know of.I wouldn't bet on it. The only way that would be true is if the diff cover is slamming hard into the front of the gas tank skid and even then I'm not sure you could make it hit.
Looking at his rear wheel in the wheel well at ride height, he definitely has the axle moved forward, so from that perspective you may be right. Are you suggesting he has everything set up right?
