It was in early 1970s that active vehicle suspension systems were developed focusing on the optimization of trade off between ride quality and road handling. If left still, the solid pieces will separate from the liquid and either fall to the bottom or rise to the top. This allows them to be removed, twisted round a few splines and reinserted, which can be used to raise or lower a car, or to compensate for the natural sag of a suspension system over time.
