Lightweight Crank Pulley for Subaru EJ Engines by Perrin

The PERRIN Lightweight Crank Pulley lightens up your rotating engine parts to free up power, a true weight savings that can be felt with every blip of the gas pedal.

Decreases Rotational Mass: The PERRIN Crank Pulley weighs 1.04 lbs., which is approximately 4 lbs. lighter than the OEM crank pulley. This reduction in weight from the crank shaft 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.

Design: 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.

Construction: The PERRIN Lightweight Crank Pulley is machined from 6061T6 billet aluminum, anodized black and laser etched for increased belt life and a precision fit.

High Performance: 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. Choose this version from the drop down menu when adding to cart.
