From the OS Giken website: "The OS Giken TR Twin Plate Clutch [TR2CD] series line-up was designed for vehicles which have substantial increases in engine power.

The billet aluminum cover provides a more direct clutch pedal feel, but still maintains ease of engagement due to the unique leverage mechanism of the diaphragm spring to reduce overall pedal effort.

The TR2CD was designed with high power turbocharged engines in mind. This type of clutch caters toward the heavily modified engines.

The dampened hub clutch discs are 215mm in size and are good up to about 800lbs ft of torque reliably. The aluminum cover allows for higher clamping force (increased capacity) and will handle the hard abuse often found at the track.

The specially designed clutch cover contains a unique leverage mechanism for the diaphragm spring, resulting in a higher clamping load of the clutch disc(s) while also reducing pedal effort. These diaphragm springs combined with our special OS Giken Release Sleeves provide a much easier to operate clutch.

Full face metallic clutch plates are utilized to achieve high torque capacity. This allows use of much softer diaphragm springs to achieve equal or better torque capacity compared to competitors with substantially less pedal effort.

Integrated ventilation holes reduce heat generated inside the clutch system and allows for friction plate dust to exit outside the clutch system, thus increasing reliability and safety.

Both the clutch housing and flywheel are chemically heat treated to handle extreme conditions. Increased power output typically requires more torque capacity(friction) in order to hold. This often leads to more heat being generated.

A hardened steel alloy flywheel provides superior durability and life than an aluminum flywheel, which also results in quicker and predictable engine response. OS Giken develops their own flywheel design to maximize their design and engineering philosophies into a no-compromise, complete clutch assembly.

The integrated clutch and flywheel package increases transmission efficiency and engine response. The clutch and flywheel was built within strict tolerances and crafted using carefully selected materials to provide the highest quality and durability."

"OS Giken offers Movement Alteration Kits to allow use of OS Giken push-type clutches on vehicles that were factory equipped with pull-type clutch systems."
