Go Fast Bits For BRZ / FR-s / 86 Lightweight Alternator Pulley - 2221
Product Description
BRAND NEW IN BOX
Lightened Underdrive BRZ/Scion Alternator Pulley
GFB Lightweight Pulleys for BRZ/FR-s/86
feature-1
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”
