Hawks Motorsports offers our clients this 780 2014-2019 Chevrolet Corvette C7 LT1 6.2L Wet Sump 6-Rib Standard Diameter Harmonic Damper, SFI 18.1, Innovators West. Designed specifically for Gen 5 LT1 engines with the wet-sump oiling system, this stock-diameter harmonic damper provides a serious upgrade over the factory piece for performance and high-RPM applications.

If you're building an LT1 and planning to make some real power, the crank damper isn't the place to cheap out. This 7.330-inch unit is built to keep the crankshaft and rotating assembly under control when the RPM starts climbing. The 6-rib drive keeps the factory-style accessory setup, while the BBC bolt pattern gives you the option to bolt on a supercharger pulley when the NA setup isn't going to cut it anymore.

The 780 exceeds SFI 18.1 standards and is marked accordingly on the front and rear of the damper. It's built around a stock-diameter 7.330-inch design and is specifically intended for Gen 5 LT1 wet-sump applications. The damper can also be configured with an optional Super Duty Blower Hub for high-power forced-induction builds.
