Yeah aftermarket wheels come in 4.25 center. The stock shafts are much larger than that. So you will need to turn the shafts down, or take the shafts out to take your wheels off. On my shafts i removed so much of the flange and you can't run washers on the bolts they leak terrible the shafts are actually warped.
Still not sure how that is cheaper than a 14b sf but have fun with it. I know i wish i woulda went SF just FYI.
