Can we ask the setup and how you broke the shaft? Did you also explode the forward hub. I replace the hub anytime I replace the shaft

We have the billet 300M input shafts in stock and ready to ship. (highly recommend)

For your power i would say you definitely need a billet clutch hub if you don't have one already and probably an upgraded drum as well if you don't already have one of those as well.
