Harmonic Balancers The original Fluidampr. Race-proven, SFI-approved steel balancer requires no service or maintenance and can help make more horsepower, run more consistently and maintain the longest possible crankshaft and bearing life. The engine feels only 2/3 of the rotating weight of the damper. Most are black zinc chromate finished with timing marks from 0° to 50°, 90°, 180° and 270°.

CT Gold Harmonic Balancers CT Gold balancers feature patent-pending centering technology (CT), which improves the control of continuous torsional vibrations due to the fact that the inertia ring remains centered in the housing cavity when the damper is at rest, al- lowing the rotating assembly to be balanced with the balancer installed on the crankshaft. SFI-approved balancers are gold zinc finished for appearance and corrosion resistance. Part No. Engine Balance Dia. Weight FLU62260D SB Chevy 262-350 Internal 6-1/4" 8.0 Lbs.

Streetdampr Harmonic Balancers Streetdampr is the economical alternative to the stock damper when an SFI-approved damper is NOT required. Extends crankshaft and bearing life, increases power and torque in street/strip engines. Streetdampr has timing marks from 0° to 40° for easy ignition timing setting and may be painted to match the engine. Part No. Engine Balance Dia.
