Secure Checkout IAG Performance Competition Series Transmission Shift Finger with Spring Pin 2004-2021 STI

Description

The Subaru STI six-speed transmission is renowned for its strength, but it is not indestructible. One of the most common points of failure is the OEM shift finger—a small component that can cause significant issues if it breaks. The IAG Shift Finger is engineered to be substantially stronger than the stock unit, providing additional support and utilizing specialized tool steel to ensure years of trouble-free operation.

Constructed from A2 tool steel, the IAG Shift Finger benefits from the exceptional toughness and dimensional stability of this material. AISI A2 Tool Steel is an air-hardening grade that contains 5% chromium, making it ideal for applications requiring high strength and reliability under stress. These characteristics ensure the shift finger can withstand the demands of aggressive driving and high-performance applications.

Designed for OEM fitment, the IAG Shift Finger installs directly inside the STI six-speed transmission without any modifications. The included FHI spring pin fits perfectly, allowing for straightforward installation and seamless integration with the existing transmission components. This upgrade ensures improved durability while maintaining the original functionality of your transmission.
