The POWERBOND RACE series brings the advantages of bonded balancers to high revving race and street/race applications where an SFI approval is required. Every POWERBOND RACE series balancer features a precision CNC machined AUS 1045 steel centre bonded to an equally strong steel inertia ring. Advanced design means that race series balancers are very light for an all steel product. An most cases they are only marginally heavier than the original cast iron balancer and generally much lighter than all steel balancers on the market. The steel inertia ring of the race series models is positively protected against forward and backward movement and has the assurance of bonded rubber to eliminate spinning. Every model has easy to read computer etched timing marks. All POWERBOND RACE series meet SFI specification 18. 1.Pit Stop USA offers Powerbond Race Performance Harmonic Balancer - Ford 302/351W - External Balance PB1060-SS at low everyday prices.
