Info

All internal combustion engines display crankshaft torsional vibration. As the piston rises and falls so does cylinder pressure. The changing pressure results in forces being transmitted along the connecting rod and applied to the crankshaft journal. The TCI Rattler counteracts those vibrations by using internal rollers that automatically offset twisting forces that cause vibration (see Fig. 1). The Rattler is an absorber that eliminates the root cause of torsional vibration. It is effective for the entire RPM range and extends crankshaft and bearing life, as well as increases valve train stability and life. The design does not utilize viscous fluids and requires virtually no maintenance. And the unit s timing marks are etched onto the body and cannot move relative to crankshaft centerline. The Rattler is also lighter in weight than most units of the same size and material construction.

This TCI Rattler Harmonic Balancer is designed to fit 3-Bolt Pulley Big Block Chevrolet engines. This balancer is for internally balanced engines only. Overall Diameter - 6.290.
