Go Fast Bits Lightweight Crank Pulley – FRS/BRZ/86

Description

Add more performance to your vehicle with the Go Fast Bits Lightweight Crank Pulley. Lightweight crank pulleys get rid of the inherent rotational mass of the heavy factory crank pulley which means you get a sharper throttle response with faster engine revs. Because the factory crankshaft in the flat 4 engine is so short, this lightweight crank pulley will not affect balance. This particular pulley saves up to 77% rotating inertia when compared to the stock pulley. 

This pulley has been fabricated from 6061-T6 aluminum alloy billet where it is then CNC machined to the exact tolerances. It is finished with an anodized black finish for extra protection against rust and corrosion. 

For a normally aspirated platform, this pulley makes for a great upgrade that will work great with any other bolt-ons you may have.
