Kartboy Aluminum Crankshaft Pulley - 02-07 WRX / 04-07 STI
Kartboy Crankshaft Pulley for the Subaru EJ Series Motor weighs in at light 2.4 Pounds. This Crankshaft Pulley is a good bit lighter than stock but not light enough to throw a CE light. This is a terrific upgrade if you are looking to free up a little crank HP and get a good looking accessory under the hood from Kartboy. This fits all EJ series Subaru engines except 2010+ Legacy GT's.
