In the world of racing and performance enthusiasts, Factory Harmonic Damper Bolts have become a major area of concern for two primary reasons. Firstly, these bolts must withstand the tremendous clamping force exerted during high RPM crankshaft flexing and twisting. Secondly, they are subjected to additional wear and tear when manually rotating the crank for tasks such as adjusting valve lash or setting timing. Frequently, this results in the bolt head becoming rounded off, leading to compromised wrenching.
