If you have an 03 to 06 Blaster, the Banshee axle is a direct swap. If you have an 02 or older with the cable operated caliper, it is NOT a direct bolt in. There is tons of misinformation around the net from people doing this. The big issue is that the older Blaster has a stationary caliper and a floating disc. The Banshee has a stationary disc and a floating caliper. When it's all over, you have only 2 good choices on the older Blasters. 1) Buy an aftermarket axle made for the Blaster. 2) Use a Banshee axle, banshee disc and hub, 03 to 06 Blaster bearing carrier, and convert it over to hydraulic rear disc brakes, including welding brackets to the frame.
