My assumption on the shackle twist is that it is similar to a "Prestressed"
bridge girder. They are bent opposite the direction of anticipated load to
counter the deflection when under load, thus arriving at a neutral camber
along the spring and thus reduced wear on the bushings and springs when in
use. I am simply making a deduction/assumption. I don't profess to be the
expert.
