2-piece underdrive pulley kit (Crank and alternator pulleys & belts. Suits WRX/STi MY94-07, Forester MY98-07, Legacy MY03-07).
The best lightweight pulley kit for SUBARU WRX MY01-02 aka bugeye--The GFB Lightweight Pulley kit or lightened underdrive pulleys 2001.
GFB lightweight underdrive pulley kit (part number 2001) is made from anodized aircraft-grade billet 6061-T6 aluminium and offers sharper throttle response and faster acceleration.
Kit includes:
GFB pulley kits are designed to improve acceleration by reducing the rotational mass (inertia) on the crankshaft as well as parasitic loads from the driven accessories. The effect is similar to a lighter flywheel, and the engine feels more lively and willing to rev.
We know that people are sometimes concerned about possible adverse effects of lightweight pulleys and underdriving, but rest assured we have done our homework! The underdrive ratios have been optimised to ensure there are NO adverse effects on the performance of the accessories, whilst it is true that some engine types do suffer harmonic issues from lightweight pulleys, we steer clear of those. The kits we release are thoroughly application tested and do NOT cause engine damage in the short or long term.
GFB products are manufactured in Australia and the company is accredited to ISO 9001, which ensures their products meet stringent quality requirements at all stages of manufacture.
GFB have Australia's best performance turbo management solutions.
