02-06 Lancer Road Race Lightweight Pullley

  • Model: RRM Light Aluminum Pulley 02-06


NEW for 02-06 Lancers - 4G94 engine.

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 HP from the engine just to spin it. Just like a light flywheel, throttle response will be greatly improved by reducing parasitic drag on the crankshaft. Research has shown that 2.7 HP is gained from every pound of weight reduced from the crankshaft. Installs in minutes and uses original belts. Professional installation is not required, however we do recommend using an impact gun to remove the main crankshaft bolt.
