a rod elongated along an axis;

a piston supported by the rod, the piston having a compression surface and a rebound surface opposite the compression surface;

a first passage extending between the piston and the rod from the compression surface to the rebound surface of the piston;

a check disc supported by the rod, the check disc movable from an unflexed position to a flexed position to increase resistance to fluid flow through the first passage;
