Interchangeable Crank Pulley Kit for LT4 Applications
2016 & Newer Cadillac CTS-V, Camaro ZL1
Innovators West Balancer with Super Duty Hub
This crank pulley kit is based on the Innovator's West Super Duty balancer assembly for the GM LT4 engine, PN 8410. 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.
The Super Duty Hub Upgrade 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.
Note 1: In the LT4 application, it is not necessary to change or relocate idler pulleys to fit crank pulley rings as large as 10.5". In select ZL1 applications, rings sized 9.55" and larger may interfere with the front sway bar.
The 9.10" kit requires the 080842HD belt. The 9.55" kit uses the K080850HD belt, and the 10.0" kit uses the K080865 belt. See our belt chart under the RESOURCES tab.
This kit does not fit the 2015 and newer Corvette Z06. One-piece overdrive balancers are available.
