Speedmaster GM LS SFI 18.1 Harmonic Balancer Damper; 25-Percent Underdrive; 5.670-Inch (Universal; Some Adaptation May Be Required)

Speedmaster Harmonic 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. The 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. | Brand:Speedmaster
