Ford used a set up like this in the transfer case on some 4 wheel drive
trucks so the parts could be available that way...

The problem there is that both sprockets are the same size, so no prop
speed reduction, there.

I don't know about all of the Chevy front wheel drive cars, but I think they
use hy-vo chains on them. I know the Chevy Citation automatic transmission
used them. I had one fail, after it was side loaded in a collision.
