Abstract
The present disclosure relates to a damper system for a vehicle. The damper system may have an electrically adjustable hydraulic shock absorber including a rod guide assembly, a pressure tube, a reserve tube and an electromechanical valve. The electromechanical valve may be disposed in a valve cavity within the shock absorber. An integrated electronic system may be included which has a power drive electronics. The power drive electronics is electrically coupled to the electromechanical valve. The integrated electronic system is disposed along an axis parallel to a longitudinal axis of the pressure tube, and at a location radially outwardly of the pressure tube adjacent the rod guide assembly.
