GFB Lightweight Pulleys for BRZ/FR-S/86
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.
By significantly reducing rotating mass, GFB lightweight pulley kits offer the following improvements:
- Sharper throttle response
- Engine feels more willing to rev
- Stronger “urge”
Specific Product Information
Description
Go faster, add lightness!
GFB’s Lightweight Pulley Kit replaces the crank, alternator, and water pump pulleys to dramatically reduce the rotating mass on the front of your FA20. This allows the engine to rev more freely and accelerate faster, giving your car a sharper, more responsive feel.

Combined, the factory steel pulleys weigh 2880g, whilst the GFB kit tips the scales at a mere 660g, representing over 2kg of rotational weight reduction!
This kit is not underdriven, so it uses the original factory belt.
