Product Details
This is the SPEC Stage 4 clutch kit, designed for the Supra MK3 with a 26-spline hub. If you're pushing significant power or plan to, this clutch is built to handle the extra torque and stress that comes with performance modifications. It's a step up from milder performance clutches, offering a higher engagement point and a firmer pedal feel, which is typical for clutches designed for high-output applications.
The Stage 4 designation means this clutch uses a sprung, multi-plate design, which helps to absorb shock and vibration while still providing a solid connection. The multi-plate setup increases the surface area for engagement, allowing it to dissipate heat more effectively and handle more torque without slipping. This is crucial when you're launching hard or dealing with sustained high-RPM driving. The 26-spline hub is specific to certain transmissions, ensuring a proper fit and engagement with your drivetrain components.
When installing a clutch like this, it's important to have all the necessary supporting components ready. This often includes a new pilot bearing, release bearing, and potentially a flywheel if yours is worn or not compatible. Because this is a Stage 4 clutch, expect a firmer pedal feel and a more abrupt engagement compared to a stock clutch. It's a well-built option for drivers who need a clutch that can reliably transfer a lot of power to the wheels.
