A spring seat is disposed about a tube which forms part of a shock absorber and supported in a predetermined position thereabout. The tube is subject to press bulge formation so that a portion of the tube becomes force fitted against a portion of the spring seat. Dies can be used to induce the formation of one or more projections which prevent the spring seat from moving axially along the tube. The force fit prevents relative rotation.

Method of mounting a spring seat on a hydraulic damping device

A piston assembly for a shock absorber comprises a piston rod which is formed with a threaded opening which extends axially and opens to an axial end, about which a piston body is mounted. A stud which is separately formed and independent of the piston rod, and extends through the piston body, engages with the threaded opening for securing the piston body thereonto.
