PowerBond Harmonic Balancer - 6.4" - SB Ford 302W EFI - 50 oz. - 4-Bolt - External Balance NC002015A 1971-1976 Pontiac FirebirdMost 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
