Just because you're running a Roots Style Blower doesn't mean you have to run a solid hub, you can STILL run a Damper and SAVE YOUR CRANK!
This 7" Diameter SFI 18.1 rated Racing Balancer is designed for Roots Blower Pulleys to bolt right up using the 2.760" bolt pattern and 2" male pulley register. It's fully engraved for setting timing and is also available with integrated flying magnet crank trigger system.
The damper comes standard with Corvette length hub.
NOTE: Innovators West specific pin kit required when used with a stock non-keyed crankshaft.

Dual Keyway Option
The double keyway option requires that the factory or aftermarket crankshaft be removed from the engine and a second keyway cut into the snout of the crankshaft. DO NOT run a double keyed damper on a crankshaft without the double keys. Failure to the damper hub can happen without the supporting key in the broached keyway slot. The dual keyway option is for Supercharged or Extreme Duty Applications (typically over 750 rwhp). Without the double key modification your crankshaft in these high horsepower applications can lead to the failure of the damper hub and/or the single keyway which results in damage to the damper and the crankshaft snout.
