Product Description
ATI Nissan R33 / R34 Super Damper for RB26 equipped models.
The patented ATI Super Damper for the RB26 Nissan R33 / R34 is the only damper designed exclusively for high performance engines.
This is recommended for any high HP motor. Each time the air/fuel mixture inside a cylinder is ignited, the combustion that occurs creates a torque spike that is applied to the crankshaft through the piston and connecting rod. This torque spike is so severe that it not only turns the crankshaft, it actually twists the crankshaft ahead of its normal rotation and then the crankshaft rebounds. This twisting action is known as torsional vibration. When these torque spikes and forces get into phase with the natural frequency, critical torsional harmonic vibrations occur and can be seriously destructive to the bearings and the crankshaft. Dampers are designed to control those destructive vibrations.
Features:
- Dampens torsional crankshaft vibrations at all RPM levels
- Protects against engine harmonics
- Laser-etched timing marks
- SFI 18.1 Certified for competition use
- Made in America
