TJ:

Not a one of those pictures show a need for a revolver shackle... NONE of those pictures show ANY wheel travel going on in the rear... Those could be STOCK rigs in those situations, and done just as well...

Come to think of it, my wife's Mazda 3 has as much travel as what's showing in those pictures. You got any useful pics to show...? None of those are coming anywhere close to even needing to use the revolvers, much less their failure points... [Finger]

But, I've got issues with your theoretical statement, earlier:

So - alot of people forget that their leaves do not push the tire down past that transition point, ....and that the axle weight is what is PULLING the tire down as opposed to the leaf PUSHING it down....
You're forgetting one very serious component, and the reason why a SOLID axle works better than IFS to begin with.

When one tire droops independent of the other, that tire is being PUSHED down by the OTHER tire. It's a fulcrum & lever. A tire doesn't just drop on a solid axle due to the weight of the axle; that's why IFS rigs have no traction at full droop. When a solid axle drops a tire, it's keeps the same traction, if not increased, because it has a nice long lever arm on a fulcrum PUSHING it down from the other side.
