Like all GFB lightweight pulleys, this one begins life as a single 6061 T6 aluminium alloy billet, and is then precision CNC machined to exacting tolerances. GFB then anodizes it black for a stealthy appearance and superior wear resistance.
This results in a large saving of 4.87 lbs. of rotating mass over the factory pulleys, without sacrificing strength or reliability. Like all GFB lightweight pulleys, you can feel the improvements:
* Sharper throttle response. * Crisper acceleration through each gear. * Retains the use of OE.
