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