You might contact Slee Offroad. I checked the Staun website and it says he is a distributor, I checked his website and found the deflators but not the beadlocks. Give him a holler and maybe he has some info on them.
They really cool thing is that even if you slice a sidewall you can still drive out on that tire if you have to. It's like an emergency spare. Don't drive to far in 4wd that way though... it might cause havoc on a x-fer case.
Junk(Mike) liked them from what I remember...I run 12psi with out a blow out yet and wheel rather hard. Bead locks would be cool to remove some worry but are low on the list of things to get in my book. But Junks rig was not really missing anything...lift,locked,geared,protected,winched,beadlocks,freezer, turbo'd twaz a sick rig to say the least.
now that I have said that I am sure it will happen.
