Trust me I actually put a hydraulic jack under the hanging kdss shock ( no sway bar connector ) and was able to lift the whole vehicle up. That’s with the vehicle running. Turn if off and it will compress the kdss shock and vehicle lowers.

Pull the plug either outside at the kdss pump. Or pull it from inside where the kdss brain is at which interrupts the power to the valves , The accumulators stay open and the piston in the shocks can now move.

You should try it. It’s not only about high speed washboard per say. I mean 13mph is not fast at all and you can def feel how much less the cab rocks. You definitely have a better understanding of all the diagrams and what’s what. But it’s like an electrical engineer never actually stepping into a building to see the insides and what not. Can you explain to me how when I tested pulling the fuse out , that it stayed stiff all the way no matter what speed and I can’t compress the shocks I’m the kdss but as soon as I turn off the truck you can.

Also about suspension /Shocks. Especially high end shocks. Yes they depend on speed. Yes on size of bump too. But speed approaching those bumps can determine how the oil flows through the piston / shims / bleed holes. So what I’m saying is shocks are velocity sensitive. And then throw a bypass shock in there and now you can be position sensitive.
