Abstract
A piston and piston rod subassembly for use with a hydraulic damper is disclosed. The piston is formed from a substantially flat blank having a pattern of bendable tabs provided along a first edge. A bendable skirt is provided along a second edge of the blank. After the blank is formed into a cylindrical body, the tabs are crimped onto a flanged end of a piston rod. A valve assembly can be retained in the cylindrical body by crimping the skirt over the valve assembly.
