Genuine OEM Audi Suspension Crossmember Insulator, part number 4M0505563F. This component plays a vital role in the vehicle's suspension system by isolating the suspension crossmember from the chassis, effectively reducing the transfer of road vibrations and noise into the cabin. It is installed within the suspension crossmember assembly, typically at mounting points. Weighing 2.668 kg and measuring 0.09 m in length, this insulator is engineered for precise fitment and damping properties. Using a genuine OEM insulator ensures the correct material composition and durometer, which are critical for maintaining factory-specified noise, vibration, and harshness (NVH) levels and overall ride quality.
