Well I poked my head under there and things seem all stock to me, but I'm not familiar with these trucks yet either. The steering arms seem to be pretty much straight, just a very slight curve inward. I noticed the inner edge of the rim is worn/ground down just a bit and looks like a 1/4" wheel spacer in there. I'll measure the wheels when I get one off again. I'm guessing they just have a rediculous back spacing since they sit about flush with the fenders.
