A piston assembly for use with an MR fluid damper. The piston assembly has a piston core and a flux ring positioned in a desired alignment with the piston core so that the flux ring forms an annular flow gap the piston core. The flux ring is secured to the piston core in the desired alignment by a plurality of projections extending across the flow gap between an inner surface of the flux ring and an outer surface of the piston core. The projections are molded through flux ring holes intersecting the inner and outer surfaces of the flux ring. A method for making the piston assembly is also described and claimed.

1. A piston assembly for use with a magneto-rheological ("MR") fluid damper comprising:a piston core having an outer surface; a flux ring having inner and outer surfaces substantially parallel to the outer surface of the piston core, the flux ring being positioned in a desired alignment with the piston core, such that the inner surface of the flux ring forms an annular flow gap with respect to the outer surface of the piston core; a plurality of projections extending across the flow gap intermediate the ends of the piston core and connecting the inner surface of the flux ring and the outer surface of the piston core for securing the flux ring in the desired alignment with the piston core.
