Lightweight aircraft grade alumimium Lightened underdrive pulley kit For MY08-on WRX/Sti

GFB lightweight underdrive pulley kit (part number 2014) is made from anodized aircraft-grade billet 6061-T6 aluminium and offers sharper throttle response and faster acceleration. Kit includes: crank, alternator and power steering pulleys, and 1 belt (the original factory A/C belt can be re-used with this kit).

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.
