GFB Lightweight Alternator Pulley - Subaru BRZ ZC6 & Toyota GT86 ZN6

The GFB Lightweight Alternator Pulley is designed as a direct replacement for the original pulley, and helps with unleasing engine power and response by reducing the inertial and driven loads.

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

GFB Lightweight Alternator Pulley features:

• Sharper throttle response (particularly off boost)
• Engine feels more willing to rev
• Stronger "urge"
