    Harmonic Damper Bolt

    Specifications:

    Manufacturer's Part Number:
    PCE292.1002

    Speedmaster Harmonic Dampers feature a strong bonding process which adheres the elastomer to the inside diameter of the steel inertia ring and the outside diameter of the hub for an improved elastomer. Also featured are clear, white, easy-to-read timing marks witha black background. At any frequency and RPM, the inertia ring harmonically rotates with the engine and absorb the torsion vibration from the rotating assembly. This process extends crankshaft and bearing life for increased engine power and torque.
