So they claim they will hit on their kit's knuckles, but the part that confuses me is why make the knuckles bigger? Seems kind of pointless, and frankly seems more like an offset issue. I don't get why a 17" rim would rub and an 18 wouldn't. Did they really make the margin of clearance THAT close? Any of y'all have 17's on a 6"? Or any upgraded spindle lift? I have a feeling it's one of those blanket statements from them because a few rims wouldn't work so therefore all 17's won't. Just like how most think our trucks can't fit 17's when really only two or three companies don't fit.
