Interchangeable Crank Pulley Kit
2009-2015 Cadillac CTS-V, 2012-2015 Camaro ZL1
Innovators West Balancer with Super Duty Hub Upgrade
This crank pulley kit is based on the Innovator's West Super Duty balancer assembly for the GM LSA engine. This kit represents a clean and simple way to add boost and horsepower to your supercharged Cadillac or Camaro without making any permanent modifications.
The SFI-approved Innovator's West balancer is precision-machined in the USA and installs directly in place of the factory unit. The 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 benefit of the wet clutch harmonics-dampening technology, which has made the Innovators West balancer 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 socket-head fasteners. Crank pulley rings are also available separately and are listed elsewhere in this section.
We installed the IW balancer and 9.55" crank pulley ring on our own CTS-V. On ProDyno's chassis dyno, the car made 547 HP at the tires, right off the street, with a very safe tune. The car showed a max boost level of 13.5 lbs (13.9 indicated on the dash gauge).
To complete your kit, please choose your desired crank pulley size below.
Note: The 8.60" & 9.10" kits will fit with the original 70mm crank idler pulley, but the 9.55", 10.00" & 10.50" crank pulleys require the use of our crank idler pulley relocation bracket to reposition the idler. This bracket is available under PN MRB1000.
The Super Duty Hub Upgrade included here is recommended for
vehicles making 750HP or more. The balancer includes a heavy-duty steel hub that mates with the crankshaft snout (where the
load is highest), and this hub is machined from a higher grade of steel and is larger
in size. A new seal is included with the
SD balancers for use in the front cover to accommodate the larger hub.
For supercharger belt length data, please see the Supercharger Belt Length Chart under our RESOURCES tab.
Note 1: The Innovator's West part number for the balancer included in this kit is 840/1000SD.
