PowerBond Street Performance Harmonic Balancers PowerBond Street Performance harmonic balancers bring bonded balancer technology within the budget of every performance street engine builder. They are also perfect for limited spec race classes, such as late model stock that require an OEM-style balancer. The bonded dampening rubber in every balancer eliminates spinning and component separation giving reliable performance in engines used up to 6,500 rpm. PowerBond Street Series balancers use high-strength SG (Spheroidal Graphite) iron rings and hubs that are pressure-bonded, and high-pressure, low-cure that features a natural rubber developed in our laboratory. All PowerBond Street Series balancers feature an etched black primer with a 2-coat clearcoat and fully etched laser timing marks.
