Engine Dampers

No more broken cranks!

Add Power, Reliability & performance; Reduce Stress by adding the “STERLING Rattler”; a torsional vibration absorber to your crank.

A high performance vibration absorber means lower vibrations, less crankshaft twist and increased power.

The Sterling Rattler is an alternative to conventional crankshaft dampers that generally dissipate vibration as heat energy.

The Sterling Rattler Torsional Vibration Absorbers are pendulum absorbers developed to control amplitudes of vibration and angle of crankshaft twist like no other design. Their ability to absorb, rather than dampen, is the key to their success. The Sterling Rattlers are effective for the entire rpm range and they extend crankshaft and bearing life. The Rattlers also allow the engine to run more smoothly, which can potentially increase valve-train stability and life. Their design does not utilize viscous fluids and they require virtually no maintenance. Although we cannot guarantee that you will never experience another cracked block or crankshaft again. Our track record however, has thus far proven a significant reduction in this risk,
