I will tell you this though if you want the extra length in the rear axle go with 300ex hubs they give you about and inch per side and give you the nice 4x110 lug pattern they will go on with just a little coaxing and a whole lot of grease I just did this on my bike and the difference in handleing is worth the money and will cost you much less than a banshee axle
What makes the banshee stock fronts better than the blaster's?
