A vehicle suspension system includes a mechanical spring portion adapted to undergo suspension deflection, a spring seat contacting and supporting the mechanical spring portion, and a mechanical gear assembly which is operatively connected to the spring seat to control spring seat position and which is adapted to be driven by an electric motor. A method for operating a vehicle suspension system undergoing suspension deflection, wherein the vehicle suspension system includes a mechanical spring portion having a spring seat with a movable spring seat position, includes determining a frequency content of the suspension deflection. The method also includes electromechanically controlling the spring seat position in response to suspension deflection when the determined frequency content is in a low-frequency range below a wheel hop frequency.
