A shock absorber with a pressure tube, a reserve tube, and a piston slidably disposed within the pressure tube to define first and second working chambers. A reservoir chamber is positioned between the pressure tube and the reserve tube. A damper baffle tube, positioned in the reservoir chamber, defines a baffle tube chamber between the pressure tube and the damper baffle tube. One or more electromechanical valves are positioned in fluid communication with the first working chamber and the baffle tube chamber. The damper baffle tube includes a compliant portion that has a sealing surface configured to move into and out of contact with the pressure tube in response to fluctuations in fluid pressure in the baffle tube chamber so as to form a check valve that holds a constrained volume of hydraulic fluid in the baffle tube chamber.
