 The Rattler®
by TCI® is a pendulum absorber developed to control amplitudes of vibration and angle of crankshaft twist like no other design. Its ability to absorb rather than dampen is the key to its success. The Rattler® is effective for the entire RPM range, and extends crankshaft and bearing life.
The Rattler® also has the ability to allow the engine to run smoother during operation, which can potentially increase valve-train stability and life. The design does not utilize viscous fluids, and requires virtually no maintenance. You can always depend on the Rattler®'s timing marks to be correct because they 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.
