Nissan TB48 ATI Custom Harmonic Damper W/12 Tooth Trigger Wheel - SK1150F

The patented ATI Super Damper is the only crankshaft damper designed exclusively for high-performance Chevy engines. The damper needs to be properly sized for the engine displacement, HP, max RPM, and application of the engine. Dampers don’t make horsepower, they allow the engine to run how it was designed to run, for the valve timing to say stable, and the engine to live longer. A couple of extra pounds on the front of the engine can actually help for performance engines.
