Overview 

The 2JZ billet crankshaft with a 94mm stroke and standard journals is a premium performance component designed for high-horsepower, high-RPM Toyota 2JZ engine builds. Machined from ultra-strong 4340 billet steel, it offers exceptional strength and fatigue resistance, far exceeding OEM and many forged counterparts. With a 94mm stroke, it increases engine displacement to approximately 3.4 liters, delivering greater torque and power potential. Precision CNC machining ensures exacting tolerances, while micropolished journals and chamfered oil holes promote excellent lubrication and reduced friction. The crankshaft features internal balancing to maintain smooth engine operation at high RPMs, and its fully profiled counterweights help minimize windage for improved efficiency. Advanced oiling design, including gun-drilled and cross-drilled passages with teardrop profiles, ensures consistent bearing lubrication under extreme conditions. Further enhanced by nitriding, shot peening, and stress relief treatments, the crankshaft is built to endure extreme boost and racing conditions, making it ideal for 1,000+ horsepower applications.
