Manley Turbo-Tuff Series forged crankshafts for Mitsubishi 4G63/4G64 and Subaru EJ20/EJ25 applications are fully machined from 4340 billet material for high-boost, high-horsepower use. Counterweights are knife-edged for precise balance, and stroker options increase displacement. Each crank undergoes stress relief, shot peening and 100% magnaflux inspection, with multi-step heat treatment and nitriding for enhanced strength and longevity.
