The Manley Turbo Tuff Billet 4340 Crankshaft for 1995-1999 Mitsubishi Eclipse 2G and 1996-2007 Lancer Evolution III-IX with 94mm Stroke is the perfect crank to built a stout 2.2L 4G63 bottom end. Each crankshaft is put through a mult-step heat treatment process and nitrided for maximum strength. The crankshaft is then stress relieved, shot peened, and magnafluxed. The center, crank pin and counterweights are gun drilled for reduced weight. Each crankshaft features knife-edged counterweights for proper balance and lowest rotational mass. Increasing the displacement of your Evo IV-IX or DSM 2G to 2.2L will not only increase lower rpm torque and horsepower but also improve turbo spool-up.
