PERRIN Crank Pulleys weigh 1.04 and 1.2 lbs., which is 4 lbs. lighter than the OEM crank pulley. This reduction in weight from the crankshaft is equal to removing more than 100+ lbs. of vehicle weight! Throttle response, horsepower, and torque are all increased with this easy-to-install part.
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, blue, 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.
Increase horsepower and torque without ECU recalibration or tune! This part is designed and tested to work safely on your vehicle without any tuning required! However, more power can be gained with proper ECU tuning! Confirm any tune or recalibration you add is specific for ALL modifications added to the vehicle. Questions? Contact Tech@PERRIN.com.
