Critical harmonic vibrations occur numerous times in a engine’s operating range. Stock rubber and elastomer-type dampers are frequency sensitive “tuned absorbers”, and work at only one critical frequency. A stock damper is tuned for a factory engine’s critical harmonic vibrations. If you change the mass of pistons, rods, or crankshaft, you change the natural frequency of the crankshaft assembly; therefore, a stock damper is no longer tuned to the new frequency of vibration. Dampers also create heat while they work. Heat and the exposure to the elements deteriorates rubber, causing it to crack and change durometer, which then leads to inertia ring slippage, damper failure, uncontrolled torsional vibration, and costly engine parts breakage.

| Torsional Vibrations or harmonics can destroy crankshafts and bearings. These vibrations rob horsepower and torque from your engine. Stock dampers utilize rubber or elastomer to control torsional vibrations. The rubbery material not only breaks down over time, but also limits the capabilities of the damper. |
