OS Giken - HR/VHR TR-Series Twin Disc Clutch (TSTDC212)

The TR Clutch series line-up was designed for vehicles which have substantial increases in engine power. This clutch is often found in time attack track cars and Pro-Am drift vehicles to handle medium to heavy engine tuning as well as the heat built up from these types of racing. 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.

Recommended for race / competition use ONLY. This clutch can be used on the street but will have a very on/off feel.

Clutch Discs

We utilize full face metallic clutch plates to achieve high torque capacity from our clutches. This allows for us to use much softer diaphragm springs to achieve equal or better torque capacity compared to our competitors with substantially less pedal effort.

Disc Weight: 1.5lbs _{(per disc)}

Clutch Cover

Our 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.

Cover Weight: 3.7lbs

Clutch Housing

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

Housing Weight (With Flywheel): 15.7lbs
