Impact suppression devices having energy absorbing capability. The devices utilize a spline configuration for two separate shafts that are movably joined such that one can move axially inside the other. The shafts themselves can act as a piston, or a piston is used as part of the components. Impact absorption is provided by a gel layer or gel layers that have hydraulic fluid properties when a force is applied to them.
