SFI Steel Race Harmonic Balancers

Our dampers are made from bulletproof 1045 steel and are designed to be installed on race engines that may rev over 10,000 rpm. Optimum damping occurs in the 6500 to 7500 rpm range They are black anodized and degreed from 0°-60° and at 90° intervals. Each balancer is individually balanced to within 4 grams or under. This is the highest standard in the industry.
This is NOT a press-fit or poured rubber. The elastomer (rubber) is bonded to the ring and hub. This process greatly increases the life and vibration absorbing capabilities. All harmonic balancers except 90000 or 90001 can be either internal or external balanced by adding or removing a balance weight.
