Perrin's lightened crank pulley for the 02-14 Subaru WRX is engineered to reduce rotating mass, increasing horsepower and torque. Made from 6061T6 aluminum and weighing 1.2lbs, Perrin crank pulley is more then 4lbs lighter then the stock crank pulley. Perrin's pulley is not underdriven and will not affect the life of your engine. The pulley is simply a redesigned, lighter version of the stock crank pulley.


Aftermarket underdrive pulleys are prone to charging and drivability problems, the Perrin pulley avoids these potential problems by exactly copying the OEM piece. The reduction at the crank shaft is effectively the same as removing 100 pounds of weight from your vehicle. Perrin's crank pulley will not wear out engine bearings or the oil pump, and will not add any additional vibration or noise. Installation is straight forward and can be done without jacking the vehicle or removing anything other than the belt cover, belts and stock crank pulley.

Awesome

I purchased the light weight pulley and i was kinda surprised on the actual weight difference on both OEM and This Light weight pulley, theres also a slight increase in throttle response(i said slight since i havent had a chance to fully drive the car) but you can feel the difference

Awesome pulley

After seeing signs of failure on my oem harmonic balancer / crank pulley and hearing the horror stories from other subaru sti owners i was beyond ready to get this thing swapped out after searching around and comparing diffrent aftermarket options I felt pretty confident in the perrin lightweight crant pulley for my ej257 and the guys at iir. Got me what i needed in a vary timely fashion for having to use ground shipping , the pulley is almost 4.3 lbs lighter then the oem steel and rubber unit not only are my revs faster and downshifts rev match easier it looks killer in the engine bay install took right around 45 mins and the directions are very helpful cant thank import image racing and Josh enough for providing exceptional service definetly will be back for more products in the near future. !!!!
