A twin tube damper assembly includes a main tube defining a fluid chamber. An external tube extends about the main tube defining a compensation chamber therebetween. A piston, slidably disposed in the fluid chamber, divides the fluid chamber into a compression chamber and a rebound chamber. A rod guide is disposed in the rebound chamber, attached to the main tube and the external tube, defining at least one channel in fluid communication with the rebound and compensation chambers. A piston rod extends through the rod guide and is attached to the piston. A pressure rate sensitive system, disposed in the rebound chamber, is attached to the rod guide in fluid communication with the at least one channel, the rebound chamber, and the compensation chamber for regulating the working fluid flow through the rod guide between the rebound and compensation chambers during compression and rebound strokes.
