Fluidampr Harmonic Dampers

Using only three parts (a laser-welded sealed housing, an internal inertia ring, and highly viscous silicone fluid between the two), SFI-approved Fluidampr harmonic dampers can control all crankshaft vibration--not just a limited frequency range. As a result, you get reduced wear on the main bearings and timing gear, more stable valvetrain operation, and less chance of crank failure.

PowerBond Race Performance Harmonic Balancers

PowerBond Race performance harmonic balancers bring the advantages of bonded balancers to high-revving and high-horsepower street/race applications where an SFI-approved balancer is required. They have been tested beyond 21,000 rpm without failure, and every balancer features a precision CNC-machined AISI 1045 forged steel hub bonded to an equally strong steel inertia ring. They are very light and in most cases, they are only marginally heavier than the original cast iron balancer. The steel inertia ring on the Race Series models is positively protected against forward and backward movement. PowerBond uses our Race Series high-pressure, low-cure that features a natural rubber developed in our laboratory. Every model has easy to read computer etched timing marks and meet SFI specification 18.1.

ATI Super Damper Supercharged Series Harmonic Balancers

These Supercharged series dampers place the powerful protection of ATI Super Damper inside of the crankshaft blower pulley. Available in 66 to 77-tooth 8mm pitch, and 40 to 51-tooth 14mm pitch, these balancers eliminate torsional crankshaft vibrations and feature dual-keyway hubs. These balancers exceed SFI 18.1 specs, have laser-engraved 360 degree timing marks, and are finished in a black zinc chromate. Numerous pulley offsets are available to keep the blower drive as close to the engine as possible, reducing the bending moment to the crankshaft nose.

TCI Rattler Torsional Vibration Absorbers

All piston engines produce crankshaft torsional vibration. TCI Rattler torsional vibration absorbers counteract those vibrations by using internal rollers that automatically offset the twisting forces and eliminate the root cause of torsional vibration. They are effective for the entire RPM range and extend crankshaft and bearing life while also increasing valvetrain stability. Their design does not utilize viscous fluids and they are lighter than most dampers of the same size and material construction. Rattler vibration absorbers feature steel rollers that fit loosely into a specific number of holes. By using an exact, patented, mathematical relationship, the rollers roll forward during the compression stroke and backward during the power stroke to keep engine speed variation and vibration to a minimum. The rollers are actually centrifugal pendulums that store and release energy back into the crankshaft rather than converting it to heat energy as dampers do. They are not frequency specific, but are based on the number of cylinders or the events per revolution so they are practical for street use, as well as track and drag strip use. Features include: * Standard bolt patterns * Available for internally and externally balanced engines * Etched integral timing marks can't move relative to the crankshaft * Maintains maximum effectiveness at all engine speeds * Virtually no maintenance required * No fluids, elastomers, or friction materials * No pulley or crank trigger shims required * CNC-machined to exact tolerances * SFI 18.1 certified
