Precision machined grooves, tightly sync with all OEM and aftermarket belts. Available for vehicles with or without air conditioning, the PERRIN Lightweight Crank Pulley fits great on all 1993 or newer Subaru EJ engines, the rear belt keeper for AC cars is minimized to make installation on 2008+ Subarus easier!
The PERRIN Lightweight Crank Pulley is machined from 6061T6 billet aluminum, anodized black or red and laser etched for increased belt life and a precision fit.
By removing the air conditioning belt drive, we have made a specialized version of our crank pulley for those building engines for the highest levels of horsepower & torque.
