Do the shockwave helix use a Yamaha bushing or is it different ?
I cant find a email to them.
 
As far as I can tell, it looks like the Shockwave helix uses the same bushing. I measured one of each that I have here, and the inside diameter and outside diameter are the same, but I did not press out the bushing from the Shockwave to see if the bushing length is the same, though I am pretty sure it would be the same. The bore that the bushing sits in on the Shockwave helix is obviously deeper, and the top of the installed bushing sat approximately .850"/21.590mm deep. Hopefully this helps!
