Harmonic Balancers - SB Chevy - Powerbond Harmonic Balancers - SBC
Most standard harmonic balancers are assembled with inserted dampening rubber which won't handle the torque forces and higher revs the modern engines generate. This leads to spinning of the inertia ring resulting in loss of timing accuracy and eventual component separation. Often these balancers are made of relatively weak Grey cast iron which often cracks in the keyways and centre webbing. Even expensive all steel or alloy performance balancers from most manufacturers use similar rubber inserts which still break down over time in the same way as standard balancers. POWERBOND balancers eliminate these common failures in standard and performance balancers by positively bonding the dampening rubber to the metal components under extreme heat and pressure.
