NEW for 2012-2013 Lancers DE/ES/SE/GT.
This is a custom ROAD/RACE CNC machined crank pulley. It is made of aircraft grade aluminum and weighs just .5 lb. Hardened steel sleeve around pulley hub assures long life. Stock pulley weighs more than 4 lbs. and robs h.p. from the engine just to spin it. Just like a light flywheel, throttle response will be greatly improved! Installs in minutes and uses original belts.
