What is the torque capacity of this SPEC clutch kit?

While SPEC does not provide a specific numerical torque rating for this P-Trim Super Twin Disc clutch, its design with two friction discs and a heavy-duty pressure plate is intended to handle significantly higher horsepower and torque than a stock clutch. It is a popular choice for high-performance 1JZGTE builds.

Does this clutch kit include everything needed for installation?

This kit includes the twin disc clutch assembly and a billet steel flywheel. It is recommended to inspect and potentially replace your pilot bearing, release bearing, and clutch fork during installation, as these are wear items and not always included in clutch kits.

What is the benefit of a twin-disc clutch over a single-disc clutch?

A twin-disc clutch utilizes two friction surfaces, which greatly increases the total friction area. This allows for a much higher torque capacity and better heat dissipation compared to a single-disc setup, making it ideal for high-power applications and repeated aggressive use.

About this part

Product Details

This SPEC P-Trim Super Twin Disc Clutch Kit is built for the 1987-1992 Toyota Supra equipped with the 1JZGTE engine and the 26 spline hub option. If you're pushing significant power through your 1JZGTE and need a clutch that can handle it, this twin-disc setup is designed to manage those demands. It's a serious upgrade for drivers looking to put down serious torque without worrying about clutch slip.

The P-Trim Super Twin Disc design uses two friction discs, which significantly increases the surface area compared to a single-disc clutch. This allows for much higher torque capacity and better heat dissipation, crucial for preventing fade during aggressive driving or repeated launches. The kit includes a billet steel flywheel, which is a solid foundation for the twin-disc setup, ensuring durability and proper balance. The pressure plate is also a heavy-duty unit, engineered to provide consistent clamping force across the entire engagement range. This well-built kit is designed to be a direct replacement for your existing clutch assembly, simplifying the installation process for a qualified mechanic.

When installing a high-performance clutch like this, it's important to ensure your flywheel is properly resurfaced or replaced, and that all associated drivetrain components are in good working order. This SPEC clutch kit is a substantial investment for your Supra, offering a robust solution for managing increased horsepower and torque. It’s a popular choice for those building a high-performance 1JZGTE for track use or spirited street driving.
