Abstract:
A suspension system for a vehicle and method for operating the same includes a shock absorber housing having a longitudinal axis, a spring disposed around the shock absorber housing, a retainer collar disposed around the shock absorber housing and an actuator engaged to the retainer collar. The actuator moves at least a portion of the retainer collar to move the spring in a direction corresponding the longitudinal axis. A switch generates a ride height position signal. A controller is coupled to the actuator and the switch. The controller controls a position of the actuator in response to the ride height position signal.
