Metco Innovators West Balancer w/10.5" Crank Pulley Ring 12-15 LSA ICPLSA-12

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 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. 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.

Notes:

• 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 the Metco Crank Idler Pulley Relocation Bracket # MRB1000.
