PERRIN PSP-ENG-104BK Lightweight Crank Pulley Black for Subaru FA/FB, WRX, Forester, Outback

PERRIN Performance Lightweight Crank Pulley – PSP-ENG-104BK (Black)

The PERRIN Lightweight Crank Pulley reduces rotating mass on FA and FB Subaru engines to free up power and sharpen throttle response. By significantly cutting weight from the crankshaft, drivers feel quicker revving and improved engine responsiveness—often compared to removing over 100 lbs of vehicle weight.
