My cousin has the same J-Arm banshee and I tried yesterday putting on some yfz450 front shocks and it will not clear the arm at all. So please dont buy the shocks because they will not fit. We are thinking of swapping out the frame for a A-arm frame it would be less expensive that way and we wont worry about the welds getting weak and breaking. It will be well worth the work because the yfz-450 shocks make a huge and I mean ahuge difference, I have a banshee with yfz450 front shocks and they are a world of a difference and all it takes is a little grinding to get them to bolt on. Hope this helps you, good luck.
