Title: Vehicle damper assembly and method of modulating fluid flow

Abstract: The invention provides a vehicle damper assembly and a method for modulating fluid flow through the same. The assembly includes a housing including a fluid carried therein. A piston is slidably carried in the housing and includes a ring and a core. At least one gap to allow fluid flow is formed between the ring and core. A rod is operably attached to the piston. The ring moves axially with respect to the core to vary the gap size and modulate fluid flow during operation of the assembly. The method includes axially moving a ring with respect to a core during assembly operation. At least one gap size is varied based on the axial movement, wherein the gap is formed between the ring and core.
