Description
GFB Lightweight Underdrive Crank Pulley (requires shorter belts) FITS SR20DET – GFB2005
GFB’s lightweight underdrive crank pulley (part number 2005) is made from anodized aircraft-grade billet 6061-T6 aluminium and offers sharper throttle response and faster acceleration. Kit includes: crank pulley only (shorter belts required).
GFB pulleys 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.
