Even more considering what d-r0ck said. Wacky that if you ask what threads a Shocker has, you can get 3-4 different answers.
Impulse threads jumped to the NXT and beyond, all the way to GOG now. I think the Nerve used these as well. Since they eventually became SP's standard, they just called them Smart Parts threads. I think GOG is trying to get it renamed as GOG threads, but we'll see how that goes. May have been a private label NXT with cocker threads.
SFT & the old Shocker Sport had the same threads. Except for a couple private label SFT's with cocker threads.
If you go way back to the pneuVentures Shocker, that one was cocker threaded.
