This kit represents a clean and simple way to add boost and horsepower to your supercharged Cadillac or ZL1 Camaro without making any permanent modifications.
The Innovator's West balancer is precision-machined in the USA and installs directly in place of the cast factory unit. The SFI-approved IW balancer and crank ring assembly weighs only 12.6 lbs, compared to 16.2 lbs for the factory steel unit. Installation of this kit removes significant rotating mass from the front of the engine, and it adds the proven wet clutch harmonics-dampening technology that makes Innovators West the premier balancer in motorsports.
Our CNC-machined crank pulley rings bolt directly to the new balancer using the provided fasteners. Once the balancer assembly is installed, changing the outer ring to adjust the boost level is simply a matter of six the allen-head fasteners. Crank pulley rings are also available separately and are listed elsewhere in this section.
Note 1: As of 6/2016, the fitment of the 8.60" (7.5% OD) and the 9.10" (13.6% OD) pulley rings have been confirmed. The use of rings sized 9.55" and larger may require additional parts and/or modifications.
Note 2: Most of the crank pulley rings can be purchased in a 10-rib configuration for custom applications.
