ABSTRACT:
A shock absorber assembly includes a piston/tube shock mechanism provided with adjustment devices permitting variation of the effective length and thus operating parameters, of a coil spring surrounding the shock mechanism. Adjustment is obtained by the vertical displacement of a member surrounding a body sleeve disposed exteriorly of the shock mechanism and wherein this vertical displacement alters the elevation of one end of the coil spring. A lock nut secures the obtained adjustment and both the member and nut may be manipulated with a simple tool cooperating with a specific configuration on the periphery of the member and nut.
