Overview 

The 1FZ cast iron crankshaft with a 108mm stroke and standard journal sizing is a durable and affordable upgrade designed to boost engine displacement and torque in Toyota 1FZ-FE applications. Constructed from strong cast iron, it provides reliable strength for naturally aspirated or mildly boosted engines where extreme performance is not the primary goal. The 108mm stroke offers a moderate increase in engine capacity, enhancing low-end torque and overall drivability. Its standard journal sizing ensures direct compatibility with OEM rods and bearings, facilitating straightforward installation and maintenance. Precision machining guarantees accurate journal tolerances for smooth operation. While heavier and less fatigue-resistant than forged or billet alternatives, this crankshaft remains a practical choice for street use and light-duty competition builds seeking improved torque and reliability at a reasonable cost.
