So, I've never had a piece of Surge-X gear open. What do they use in place of MOV's?

A sealed package from Marie Laveau's House of Voodoo in NOLA.  You DONT want to open it.  Ever.  8)

Essentially really big series inductors that present a high impedance path for voltage spikes with a fast rise time. This is the opposite of MOV devices that short out the voltage spike to the ground when the peak voltage goes over the design threshold.

I liked the gris-gris bag...

But your explanation has that science thing going for it.

Sounds just like the chokes in a 20 amp or 50 amp dimmer using SCRs or  solid state relays!

I may have snarfed my coffee reading that.  Thanks, Tim.   :o
