The ones for the rear xxxt-sc (2w truck) are somewhat wider that the stock sc10 4w wheels. The only thing you need to be careful about is that the rim is thicker also so the axle might not be long enough to get in the nylock part of the wheel nut. I don't physically have the wheels yet; the info I have is what I have been told by Dave at DE Racing so I am going to do some testing when I get a couple of sets to play with.
