A vibration isolation system (208) for an advancing blade concept rotorcraft (200) having a pylon assembly (202) and an airframe (222). The vibration isolation system (208) includes one or more pylon links (210; 212) each having first and second ends with the first end (214; 216) coupled to the pylon assembly (202) and the second end (218; 220) coupled to the airframe (22). Each pylon link (210; 212) includes a vibration isolator (228; 230), such as a Liquid Inertia Vibration Eliminator unit (232), that is interposed between the pylon assembly (202) and the airframe (222). The vibration isolator system (208) is operable to reduce or eliminate transmission of the pylon assembly (202) vibration to the airframe (222).
