The present disclosure relates to a shock absorber having a pressure tube forming a pressure chamber. A piston rod is disposed within the pressure chamber. A reserve tube defines a reserve chamber adjacent the pressure tube. A rod guide assembly is concentrically disposed about the piston rod and the pressure chamber and houses a plurality of digital valves. Each one of the digital valves includes a component which is moveable between an open state and a closed state, and thus helps to control a fluid flow between the pressure chamber and the reserve chamber. An electronic control system is disposed on a printed circuit board assembly (PCBA) and controls actuation of the digital valves. At least one additional valve is associated with one of the digital valves for further controlling a flow of fluid between the pressure chamber and the reserve chamber.
