Professional Products Powerforce+Plus line of harmonic balancers meet SFI Specifications which allows them to be used in organized racing events. Made of maximum strength 1045 steel, these are the ultimate in a racing balancer.

These balancers are designed so that if an unlikely failure allows the inertia ring to come loose, it is captured onto the hub and cannot fly off. This is the ultimate racing damper but can also be used on street applications.
