A true weight savings that can be felt with every blip of the gas pedal. One of our best selling parts, many thousands installed on Subaru engines around the world.
Decreases Rotational Mass
The PERRIN Performance Crank Pulley weighs just 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.
Precision machined grooves, tightly sync with all OEM and aftermarket belts. While the PERRIN Performance crank pulley fits great on all 1993 or newer Subaru boxer engines, the rear belt keeper is now minimized to make installation on 2008+ Subarus easier!
The PERRIN crank pulley is machined from 6061T6 billet aluminum, anodized black or red and laser etched for increased belt life and a precision fit.
Gates 2008-2016 Stretch Fit Belt Installation Tool
Subaru utilizes stretch fit belts which are shorter than the actual working length, but once they are installed they automatically tension, maintaining the proper tension over the life of the belt and ensuring optimum load-carrying capacity. The Gates installation tool is required to properly guide the belt onto the pulley and avoid damaging the belt.
