Types of differentials/Traction aiding devices

[Todd....!!]

OK, sounds like an all around GREAT alternative to a spool....

Better gas mileage, almost as strong, NUTHIN's stronger than a spool...
right?

Where does the air go into the rear gear area, and what creates the air
pressure? Some sorta pump, I assume?

What all rearends is this technology built to accomodate?

May it be applied to an 8 3/4 or Dana 60, or even a Ford 9 incher?

Just wonderin.....
