Henry,
I called the manufacturer, and a couple of the sellers listed on their web
page, and their staffs weren't much help in explaining how it works. One
gave me a url for a Mopar tech page which I posted to the list, and in there
they discuss grinding the Mopar spider gears flat for a better surface for
the Phantom Grip to push on. They sell different springs, with Gold being
stiffer than the green they list for the TR series, so it's tune-able. It
looks like a pretty simple deal, with the plates spinning up and releasing
whenever a wheel slips. What I can't tell is if the plates are pressed
outward with centrifugal force onto the spider gears to lock each side of
the diff. or the spinning overcomes the spring tension and releases pressure
on the spider gears which somehow locks it. I hope somebody comes up with
an explanation. The price and the function seems to good to be true.
Bob
