Lightweight Alternator Pulley for FA20 BRZ/FR-S/86.

The GFB Lightweight Alternator Pulley can be used stand-alone, or as a spare/replacement for the alternator pulley in the 2016 3-piece pulley kit.

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.

By significantly reducing rotating mass, GFB lightweight pulley kits offer the following improvements:
  • Sharper throttle response
  • Engine feels more willing to rev
  • Stronger urge
