A novel and improved magnetorheological fluid damper is provided which effectively secures a flux ring to a piston core in a manner which prevents relative axial and radial movement between the flux ring and the core throughout operation. The damper includes crimp portions formed on each end of the flux ring for engaging respective end plates positioned at each end of the piston core to secure the end plates and thus the flux ring to the piston core. One of the end plates may, in turn, function to maintain a piston rod in connection with the piston core. Specifically, each end plate functions as a spring device by being elastically deformed during a crimping process causing the end plates to apply a spring force against the flux ring. One of the end plates may also apply another spring force to the piston rod. A crimping method is also provided which effectively and efficiently permits crimping in a simple manner.
