GFB Lightweight Underdrive Crank Pulley - Nissan 300ZX

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.

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

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