Save your engine from complete timing failure from dropped timing belt with this performance-designed IE/ARP Crankshaft Damper Bolt Upgrade. 


The factory installed crank damper and timing belt drive gear interface is one of the highest failure issues with the VW & Audi 20V 1.8T and 12V 2.0T FSI engines. This timing interface does not have a safety factor from the factory and commonly leads to lost timing and complete engine failures. This issue is only increased on performance engines when combined with higher RPM. The factory bolts are frequently shipped loosely without thread protection. leading to erratic clamping loads and further resulting in engine failure rates.


This IE designed and ARP manufactured Crank Damper Bolt addresses all the issues with under-spec factory bolt providing a strong, reliable, and quality upgrade solution. Manufactured from aerospace grade materials resulting in extremely consistent thread quality and strength. This timing increases clamping loads by over 10%, reliably ensuring a slip-free interface and protection against sheared timing gear keyways.



  • Using a 13/16” 12 point drive and quality verified torque wrench, torque your new IE/ARP crank bolt to 78 FT-LB + 1/4 turn using red Loctite®.


  • The final 1/4 turn equates to a lot of torque, this requires a long bar to complete the turn, be prepared.
  • Thoughrouly clean and inspect the threads in the crankshaft ensuring they are clean and free of debris before installing your bolt.
  • This IE ARP bolt is reusable if for any reason you need to remove it, heat the bolt interface before removing without exceeding 400 degrees Fahrenheit.
