Product Description

The OS Giken TY021-BF6 is a high-performance twin-plate clutch engineered for Toyota JZ-powered platforms such as the JZA70 Supra and early Soarer models. Built for demanding street, drift, and track environments, it delivers exceptional torque capacity, rapid engagement, and improved pedal feel through its finely balanced TR2CD twin-disc design.

A billet aluminum cover enhances structural strength and heat resistance, while the dampened hub reduces noise and drivetrain shock during aggressive shifts. For proper installation, the TY021-ALT25 Movement Alteration Kit is required to ensure correct clutch actuation and release geometry--an essential component for reliable operation on R154-style transmissions.
