Genuine OEM Volkswagen radiator mount, part number 4F0121276. This rubber bushing acts as a vibration damper, securing the radiator to the vehicle frame while isolating it from engine and road-induced vibrations. It is designed with specific durometer rubber to provide the correct balance of flexibility and support. Genuine OEM mounts are essential to prevent premature radiator fatigue, cracking, or misalignment caused by improper vibration dampening.
