Product Description

The ATI 918607 Super Damper Harmonic Balancer is a high-performance crankshaft damper engineered to control torsional vibration in Nissan SR20 2.0 L front-wheel-drive engines, including both naturally aspirated SR20DE and turbocharged SR20DET variants. By damping crankshaft harmonics across the RPM range, this damper helps protect critical engine components and can improve durability and power delivery in street and performance builds. The black zinc chromate finish and laser-etched 360° timing marks also provide useful durability and timing reference features for tuners and engine builders.

Built with an aluminum outer shell and a robust steel hub, the ATI 918607 exceeds SFI 18.1 specifications, making it suitable for high-RPM, high-stress applications where stock dampers may fall short. It retains OEM accessory drive groove locations so it integrates with factory serpentine belts and accessories with minimal modification. Ideal for enthusiasts upgrading or building high-output SR20 engines, this Super Damper offers both functional vibration control and strong construction in one precision-engineered component.
