Integrated clutch and flywheel packages increase transmission efficiency and engine response. Our clutches and flywheels are built within strict tolerances and crafted using carefully selected materials to provide the highest quality and durability. It is highly recommended to not go beyond 70%-80% of the clutch's maximum capacity to endure longevity of the clutch.
Super Single Clutch series is an ideal choice as a replacement to the original equipment clutch and flywheel and provides your vehicle with quicker response and higher performance. The Super Single Clutch is designed with the same high-quality materials and strict manufacturing processes as Racing Multi-plate Clutch line.
The Grand Touring Clutch is our latest development to our clutch lineup. It retains the technology from our Multi-plate Clutches, but with the addition of our unique floating pressure system to provide a smooth and chatter-free driving experience. The Grand Touring Clutches are available in single and twin plate configurations, and can be matched with a soft or hard clutch cover to suit the engine output.
The STR Clutch line-up was designed to hold high capacity power while still retaining a relatively light clutch pedal. This technology was driven from our racer's demand for a lighter clutch during long endurance races in Japan. Heavy clutch pedals lead to driver fatigue during long endurance racing. Available in single and twin plate configurations matched with a unique clutch cover which allows for factory like clutch pedal feel.
The TS Clutch Series line-up is the original technology used since the birth of OS Giken. This style of clutch has stood the test of time for good reason. It is capable of handling light to medium engine tuning. Most tuners will find this clutch suitable for their power figures. The stamped steel cover maintains a moderate pedal effort for the given capacity it can hold, while the heat-treated alloy clutch discs improve durability and maximize performance.
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.
The R Clutch series line-up is our highest capacity clutch and is specifically designed for vehicles with a significant increase in engine power. Our unique floating center hub design is built to withstand transmission shock and abuse from high-powered racecars. These clutches can be found in multiple leading Formula D drift vehicles as well as top leading Drag Racing production vehicles. These clutches are available as twin, triple, and quadruple plate assemblies for the most popular high power engines around the world.
