Zerosports WRC Crank Pulley Subaru WRX STI 02-07

The Zero/Sports WRC Pulley is a direct replacement for the WRX/STi crankshaft pulley.

WRC Crank Pulley Features:
-The factory pulley weighs in at a heavy 5.4 pounds and is a perfect place to shed some weight. Removing weight from a moving part of the engine is even more critical than removing dead weight from any other part of a car.
-Removing the weight from the pulley allows the engine to move faster with less effort, allowing for faster revving response and the production of more horsepower and torque.
-The Zero/Sports pulley, made of lightweight aluminum, weighs in at a very light 1.4 pounds.
-The pulley will remove a full four pounds of weight from your engine, which adds up to a big difference!
