Description
The GFB Lightweight Crank, Power Steering & Alternator Pulley Kit is designed as a replacement for the original pulleys and increases engine power and response by reducing the inertial and driven loads.
Like all GFB lightweight pulleys, begin life as a single 6061 aluminium alloy billet, and is then precision CNC machined to exacting tolerances. GFB then anodize them black for a stealthy appearance and superior wear resistance.
Shaped to look exactly like the factory Subaru originals, so they go unnoticed in the engine bay.
Kit includes 3 pulleys with necessary belts, and is suitable for all Subaru EJ-series engines.
GFB Lightweight Crank, Power Steering & Alternator Pulley Kit features:
- Sharper throttle response (particularly off boost)
- Engine feels more willing to rev
- Stronger "urge"
