well i was curious to this a couple months ago if the yfz hubs would fit well since i just got a yfz i thought i would try it out to see and they will fit just a tad tighter than the blasty hubs but they will go on and the rear. the model im working with is 06-07 so i would imagine from 04-08 hubs will fit if you happen to want to change your bolt pattern here is another option
