ABSTRACT A dampening shock absorber (10) for retrofit or original construction with a conventional gas charged or hydraulic shock absorber or strut having an annular sleeve (14) telescoped in sliding engagement over an inner sleeve (13) to provide therewith a spring biasing to return the shock absorber to a null state after a displacing force has been removed therefrom. The spring biasing is provided by a single coil spring (26) that is telescoped over an annular sleeve of that shock absorber that has at least a pair of longitudinal slots (17) removed therefrom, which coil spring ends are maintained between outwardly extending flanges of a pair of sliding retaining clips (18) and (19) that are telescoped over said annular sleeve that also include inwardly projecting fingers (20) and (21), said fingers each to engage a slot end and extend therebeyond so as to engage an inner side or edge of one of a pair of guide rings (28a) and (28b) that are secured in spaced arrangement around the inner sleeve, the distance between which opposite guide ring inner sides is equal to the longitudinal slot length. The inwardly projecting fingers are thereby in overlapping engagement with the longitudinal slot ends for maintaining retaining clip positioning with the coil spring compressed therebetween, the relationship between which retaining clip fingers, longitudinal slot ends, and guide rings inner sides or edges to provide for sliding movement of the retaining clips towards one another so as to compress the coil spring therebetween when the inner and annular sleeves are telescoped together or pulled apart.
