OS Giken Toyota COROLLA 4AG TS Series Twin Plate Clutch

The OS Giken TS Series twin plate clutch is built with a unique sprung center hub design, which helps absorb drivetrain shock and reduce noise compared to many other performance clutches. This is a serious upgrade for your 1988-1991 Toyota Corolla, especially if you've modified the engine for more power or are looking for a more direct connection to the drivetrain. OS Giken is well-known for its high-performance clutch systems, and this twin plate setup is designed to handle significant increases in torque and horsepower.

This clutch kit features two friction discs, which distribute the clamping force over a larger area. This not only increases the torque capacity but also helps to reduce clutch disc wear, making it a more durable option for demanding use. The pressure plate is engineered for consistent engagement, providing a solid feel at the pedal that lets you know exactly where the clutch is biting. Because it's a twin plate design, you can expect a more immediate engagement than a single plate clutch, which is beneficial for spirited driving and track use. The sprung center hub is a notable detail that sets this clutch apart, offering a smoother engagement feel and better protection for your transmission and differential.

When installing a twin plate clutch like this, it's important to ensure your flywheel is resurfaced or replaced to meet the specific requirements of the clutch kit. OS Giken recommends using their specific alignment tool for proper installation. This clutch is designed to be a direct replacement for the stock clutch assembly, but due to its performance nature, it will have a different engagement feel and may require some adjustment in driving technique. It's a well-built component that offers a significant improvement in performance and durability for your Corolla's drivetrain.
