Hawks Motorsports offers our clients this 850 LSX 6-Rib Harmonic Balancer for 2006-2013 Corvette LS7, Standard Diameter, Innovators West. This SFI 18.1 harmonic balancer is designed for the LS7 Corvette and features a 6-rib drive with the standard 7.25-inch pulley diameter. A crank bolt and single 3/16-inch keyway are included.

For an LS7 that needs a solid crank damper without changing the factory belt ratio, this is the straightforward way to go. The 6-rib pulley keeps the accessory drive familiar while the SFI-rated damper gives a serious engine build the kind of crankshaft control you want when the RPM starts climbing. It's a clean choice for a naturally aspirated LS7, road-race setup, street car, or a build where you're sticking with the factory-style 6-rib drive.

The 7.25-inch standard diameter keeps the stock pulley ratio, and the balancer weighs approximately 7.4 lbs. It comes with a single 3/16-inch keyway and can be ordered with an optional second keyway for applications that require additional crankshaft retention.
