CTS Crank Pulley Kit - 2.0T-FSI (EA113)
Like all GFB lightweight pulleys, this one begins life as a single T6061 alloy billet, and is then precision machined by CNC to exacting tolerances. It's then anodize it black for a stealthy appearance and superior wear resistance.
This results in a large saving of 1.4kg of rotating mass over the factory pulley, without sacrificing strength or reliability.
