Speedmaster Harmonic dampers are manufactured from forged K1045 low carbon steel and tuned elastomer between the two layers of steel. These dampers feature a bonding process which adheres the elastomer to the i.d. of the inertia ring and the o.d. of the hub, utilizing a strong adhesive along with an improved elastomer to create a much stronger bond. They also feature clear, white, easy-to-read timing marks against a painted black background. The steel inertia ring rotates harmonically with the engine and absorbs the torsion vibration from the rotating assembly at any frequency and RPM. It extends the life of crankshaft and bearing which allows the engine to produce more power and torque. This damper is internal balanced; the term internal balanced damper refers to the lack of any built in weight or offset in the casting. When identifying your existing damper, (balancer) you must look on the backside. This is not visible if the damper is mounted on the engine.
