Claim 11:
12. A method of controlling a suspension system of a vehicle, said suspension system comprising a shock absorber housing having a longitudinal axis, a spring disposed around the shock absorber housing and a retainer collar disposed around the shock absorber housing, an actuator engaged to the retainer collar, wherein said actuator comprises a motor coupled to the retainer collar and a first seal disposed between the shock absorber housing and the retainer collar and a second seal disposed between a flanged extension and the retainer collar, said shock absorber housing comprising first external threads and the retainer collar comprises internal threads engaging the first external threads, the first external threads disposed within a flanged extension disposed at a first end of the shock absorber housing, said method comprising:
generating a sensor signal corresponding to a sensed condition at or near the shock absorber with a sensor;
moving at least a portion of the retainer collar by way of the actuator to move the spring in a direction corresponding to the longitudinal axis;
rotating, by way of the motor, the retainer collar around the longitudinal axis based on the sensed condition so that the internal threads move relative to the first external threads; and
moving the spring in the longitudinal direction in response to rotating the retainer collar.
