Powerbond Race 5% Overdrive Harmonic Balancer To Suit Holden Ecotec L36 L67 Supercharged 3.8L V6

This Powerbond Race 5% Overdrive balancer brings the advantages of a bonded balancer to high revving race and street/race applications where an SFI approved balancer is required. Every Race series Powerbond balancer features a precision CNC machined AUSI 1045 forged steel hub bonded to an equally strong steel inertia ring. Advanced design means that Race series balancers are very light for an all steel product. In most cases they are only marginally heavier than the original cast iron balancer and generally much lighter than other 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 balancers meet SFI specification 18.1.
