GFB Underdrive Pulley Kit WRX/STi 03-07, Forester XT 03-08
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”
