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.
The R3C Clutch is specifically designed for vehicles with a significant increase in engine power and torque. It is capable of handling up to 1100lbs ft of torque and immense amounts of heat. This clutch is often found in our competition drift and drag vehicles. Our unique floating dampened center hub design is built to withstand transmission shock and abuse from high-powered racecars.
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.
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.
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
FLYWHEEL
Our hardened steel alloy flywheels provide superior durability and life than aluminum flywheels, which also results in quicker and predictable engine response. We develop our own flywheel design to maximize our design and engineering philosophies into a no-compromise, complete clutch assembly.
Our 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.
Included Components
Triple Plate Clutch Assembly with Flywheel

Requires SB041-ALT
Please consult installation guide
Requires OEM Pilot Bearing or Bushing
NOTE: THIS KIT REQUIRES(NOT INCLUDED!) THE OS GIKEN "MOVE ALT KIT" WHICH REPLACES YOUR STOCK CLUTCH FORK AND SLAVE CYLINDER.
Movement Alteration Kit
"OS Giken supplies a Movement Alteration Kit to allow the use of a push-type clutch on vehicles that are factory equipped with pull-type clutch systems. Please note that the OS Giken Movement Alteration Kit is designed to work with OS Giken clutches, and installation to unintended applications may result in failure of clutch components."
WARNING: Operating, servicing and maintaining a passenger vehicle or off-road vehicle can expose you to chemicals including engine exhaust, carbon monoxide, phthalates, and lead, which are known to the State of California to cause cancer and birth defects or other reproductive harm. To minimize exposure, avoid breathing exhaust, do not idle the engine except as necessary, service your vehicle in a well-ventilated area and wear gloves or wash your hands frequently when servicing your vehicle.
