Interchangeable Crank Pulley Kit

2009-Newer CTS-V, 2012-Newer ZL1 Camaro

This crank pulley kit is based on the Innovator's West replacement 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 ZL1 without making any permanent modifications. 

The 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. 

Metco's 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.

Metco installed the IW balancer, 9.55" crank pulley ring, and 50mm idler pulley on Metco's 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 (All sizes are listed in the Pumps & Pulleys section). 

Note:  The 9.10" and the 9.55" crank pulley rings require the use of Metco's reduced diameter idler pulley, listed elsewhere in this section.  The 10.00" & 10.50" crank pulleys require the use of Metco's crank idler pulley relocation bracket (with the 50mm idler pulley).
