GFB Lightweight Crank Pulley Subaru WRX/STI/FXT/LGT (EJ20/EJ25)
GFB has re-engineered its popular lightweight crank pulley to look factory standard while cutting a serious amount of rotating mass. Designed for the Subaru WRX, STI, Forester XT and Liberty GT running EJ20 or EJ25 engines, it sheds weight from the rim to sharpen throttle response and let the engine rev more freely, all while using your factory belts.
This listing covers all EJ-series Subarus including GC, GF, GD and GG Impreza WRX and STI models, GE, GH, GR and GRB hatch and sedan variants, BE, BH, BL and BP Liberty GT and B4, and SF, SG and SH Forester XT chassis. SKU 2009.
