First off the spindles won't fit on the banshee knuckle. But the 450/raptor knuckles and spindles will fit on a banshee.But there are some other parts you'll need +2 brake lines yah can use stockers but they are kind of streched and barly fit. Plus some +2 tie rods. But not a bad way to incress the width of your bike and lieghen sprung weight and bike weight. it's about 2 pounds a side. Just thought i WOuld let yah know about the spindles, And thanks for telling us about the brake calipers. Soon it will be there will be no stock parts wuahahahahhaha
