OS Giken has developed a versatile clutch that addresses a wide array of requirements, catering to imported cars as well as high-power vehicles that exceed 1000 horsepower.

For installation, please follow the maintenance manual for each manufacturer's applicable model.

If there is no other manufacturer's (special order item, etc.)
instructions, please use the manufacturer's genuine product. (For instructions, please refer to the attached sheet.)

When overhauling, basically replace the disc pressure center plate (single plate is not used) at the same time.
Since the disk may be distorted or changed in properties due to heat, replacing only the disk will not only cause uneven contact between the pressure plate / center plate (single plate is not used) and the disk contact surface, but also reduce the contact area of ​​the disk. The ratio will be lower and the transmission capacity will be significantly reduced. As a result, 100% of the transmission capacity cannot be transmitted, causing immediate slippage and poor cutting.
When overhauling, it is recommended to replace the disc and pressure plate center plate (single is not used) at the same time.

[Overhaul KlT・A] & [Overhaul KlT・B] are available

K1T・A…Disc pressure center cover mounting bolts

*When performing an overhaul, there are items to check such as the type, model, type, and engraving of the clutch currently in use.

Founder Masaharu Okazaki founded the Okazaki Speed ​​Technology Research Institute. In the early 1970s, while tuning motorcycles and automobiles on the market, his lifework, high rpm, high output, gathered the best of his own theory and technology. Succeeded in developing the original engine TC16-MA1. However, because of its high output, the off-the-shelf clutch, transmission, and differential gear that transmits power to the final drive wheels make noise. In order to transmit the maximum output of the engine to the end, his extraordinary passion that "if it breaks, make something that won't break" and the belief that "you won't know until you try" continue to today's OS Giken. It has been inherited and transformed into products.
