All the Yammy sport quads have same spline on hubs, but you have to ditch Blaster wheels as they have different bolt pattern. Which isn't a bad thing as the 9" wheels gives a greater choice of tires.
I don't have a blaster, I'm aware of the 4x100 having less options. the 85/86 LT250r have the same spline as the banshee. so whatever fits that works on them too I thought only raptor 660, banshee and warrior shared the same axle spline count/size? raptor 700 hubs work as well as yfz cool, easier to find a set of hubs for cheap lol
