GFB Lightened Underdrive BRZ/Scion Alternator Pulley

 

Like all GFB lightweight pulleys, these begin life as a single 6061-T6 aluminium alloy billet, which is then precision CNC machined to exacting tolerances. We then anodize them black for a stealthy appearance and superior wear resistance.

The weight doesn’t tell the whole story either – even though the saving is a significant 77%, the actual rotating inertia reduction (inertia is what counts) is 83%.

Like all GFB lightweight pulley kits, you can feel the improvements:

  • Sharper throttle response
  • Engine feels more willing to rev
  • Stronger “urge”
