1. A gas cup for a damper assembly comprising:
a body including an upper surface, a lower surface, an exterior surface and an interior surface;
said body defining an aperture extending through said upper surface and said lower surface;
a decoupler located in said aperture and secured to said body; and
a bridging member located between said decoupler and said body and coupled to said decoupler and said body, said decoupler and said bridging member being made from materials having different elasticity to allow said decoupler to move in said aperture in response to a volumetric change in the damper assembly and to provide variable tuning of the damper assembly,
wherein the gas cup further includes at least one stopper located in said aperture and coupled to said interior surface for restricting movement of said decoupler,
wherein said at least one stopper includes an upper stopper and a lower stopper, said upper stopper being located adjacent to said upper surface and coupled to said body for restricting an axial movement of said decoupler toward said upper surface; and
said lower stopper being located adjacent to said lower surface and coupled to said body for restricting an axial movement of said decoupler toward said lower surface,
wherein said upper stopper defines a first orifice bounded by a first periphery, said first periphery extends about a center axis and includes at least one first peak and at least one first trough.
