Description
DECREASE ROTATIONAL MASS
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 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
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!
CONSTRUCTION
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.
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.
