This is a genuine RUOTA FONICA for Fiat, Alfa Romeo, and Lancia vehicles, identified by part code 55221390. The RUOTA FONICA, also known as a tone ring or reluctor ring, is a critical component for your vehicle's Anti-lock Braking System (ABS) and traction control systems. It is precisely engineered with specific tooth patterns that allow the ABS sensors to accurately measure the rotational speed of the wheel. This data is essential for the vehicle's computer to detect wheel lock-up during braking or loss of traction, enabling the ABS and traction control systems to intervene effectively and maintain vehicle stability and control. Replacing a damaged or worn RUOTA FONICA is crucial for the optimal performance and safety of your vehicle's braking and stability systems. Ensure you are purchasing the correct part for your specific Fiat, Alfa Romeo, or Lancia model to guarantee compatibility and reliable operation.
