The Manley Turbo Tuff Billet 4340 Crankshaft for 2008-2015 Mitsubishi Evo X 4B11T with 94mm Stroke is the perfect crank to build a stout 2.2L 4B11T 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 X to 2.2L will not only increase lower rpm torque and horsepower but also improve turbo spool-up.
