The GFB Lightweight Crank Pulley & Alternator Pulley Kit allows for sharper throttle response (particularly off boost), as well as providing a large saving of 1.4kg of rotating mass over the factory pulley, without sacrificing strength or reliability!

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

GFB Lightweight Crank Pulley features:

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