The best thing to do would be to put them in a box within a box, with some packing material between. I have received kegs that were in just one box. It's a crapshoot then. If you completely surround them with newspaper or packing peanuts - chances are they will do fine.

I recently purchased 4 reconditioned kegs from B3 in a single box with losta bubble wrap.
They are having troubles with their regulator supplier at the moment, but it has given me time to make some design modifications. Damn the person that posted that McMaster's link for the replacement o-rings. I am finding many other parts there as well too.
