GFB Lightened Underdriven Subaru BRZ and Toyota GT86 Alternator Pulley 2221

GFB Lightened Underdriven Subaru BRZ and Toyota GT86 Alternator Pulley 2221

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.

This kit is supplied with 3 pulleys, not just for looks - the combined saving of 2.2 kg is significantly more than what is achieved by replacing just the crank pulley alone.

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”

Suitable for:

• Subaru BRZ Rear Wheel Drive (2012 and later)
• Toyota Gt86 Rear Wheel Drive (2012 and later)
