Hawks Motorsports offers our clients this 844 LSX 10-Rib Harmonic Damper for Corvette, Pontiac G8 and CTS-V, 10% Overdrive, Innovators West. This SFI 18.1 harmonic damper is designed for LS1, LS2, LS3 and LS6 wet-sump engines in Corvette, Pontiac G8 and Cadillac CTS-V applications. It features a 10-rib drive, 10% overdrive pulley, 8.125-inch diameter and includes a crank bolt.

If you're leaning on an LS with a blower, the crank pulley is where the whole belt-drive party starts. This 844 puts a serious 10-rib drive at the crank and spins the supercharger 10% harder without resorting to an even smaller blower pulley. More belt contact means more grip when you're making real power, and the larger 8.125-inch pulley gives the setup the overdrive needed to wake up the blower.

The damper uses a 3/16-inch keyway, exceeds SFI 18.1 standards, and is available with an optional dual-keyway setup or Super Duty Blower Hub for higher-output applications. Innovators West recommends the Super Duty Blower Hub for supercharged combinations producing 750+ rear-wheel horsepower.
