A hydraulic damper () includes a tube () filled with working liquid, wherein at least one end of the tube () is provided with a narrower section () of a smaller diameter provided with at least one axial groove (). The damper () includes at least one additional piston assembly () having diameter (D) smaller than diameter (D) of the main section of the tube (), displaceable along with the main piston assembly () and apt to be introduced in the narrower section of the tube () to generate additional damping force. The narrower section () extends through a conical section () into the main section () of the tube () and the conical section () of the tube () is internally shaped to form axial bridges () defining said axial grooves () extending along the length of said conical section (), each comprising a cylindrical section ().
