Pull-Type Operation: Available for select car models. It offers light pedal effort and high transmission power, similar to the original equipment, while enhancing responsiveness.

SINGLE DISC Clutch: A High Utility Clutch Series

This clutch was developed based on feedback gathered from race support, incorporating ORC’s expertise in design. Since its release, the clutch technology has been praised by users for being “easy to ride.”

Designed for lightly tuned cars, the high-performance single clutch comes in two models: the 309 and 409 Series, depending on the vehicle. We have achieved excellent pedal feel, reliable torque transmission, and offer these clutches at a competitive price. Our lineup includes a variety of options to fit different needs, such as a silent type to reduce backlash noise, a damperless type for enhanced response, and a high-torque disc version.

TWIN DISC Clutch: High-Performance Series

The twin disc series is renowned for its exceptional performance and widespread popularity. It offers outstanding pedal feel for high-powered vehicles.

The 559 models provide a balance of transmission power, sharpness, and half-clutch feel. The 659 models offer higher torque capacity.

TRIPLE DISC Clutch: Extreme-Performance Series

The triple disc high-capacity clutch is designed to minimize changes in the engagement point while enhancing sharpness. Built for durability and reliability, it’s engineered to withstand the demands of drag competitions.

QUIET TYPE:
Suppresses backlash noise
(optional for single clutch)

QUIET TYPE
A quiet version is available as an option, designed to suppress the chattering noise typically associated with lug drive clutches when disengaged. The inclusion of a coil spring helps press down the pressure plate, reducing vibrations. This spring also aids in returning the pressure plate to the cover side, enhancing the clutch’s disengagement performance.

DAMPERLESS TYPE:
Excellent response during engagement
(optional for single and twin clutches)

DAMPERLESS TYPE
The standard model prioritizes operability by using a damper-equipped disc, while a damperless option is available for those seeking faster response in competitive settings. This provides a more direct transmission feel. Note: The damperless type has a more severe half-clutch than the damper type.

HIGH µ DISC TYPE:
Higher safety factor
(optional for some single clutch 409 Series models)

DAMPERLESS TYPE
This model features a high-speed disc specifically developed for drag racing to enhance torque output. Note: The high-friction (high µ) disc has a more aggressive half-clutch engagement compared to standard discs.

PULL TYPE operation method:
Available for some, but not all, car models.
 

PULL TYPE
The optional pull-type operation method achieves a light pedal force and high torque transmission similar to that of the stock product, and improves sharpness.

SLIT PROCESSING:
Realizes stable torque transmission
(For Twin/Triple Disc Clutch)

SLIT PROCESSING
To address heat management, slits were added to the friction surfaces of the pressure and mid plates, segmenting each surface. These slits provide a cooling effect, and the segmentation ensures more uniform contact, resulting in stable torque transmission.

FLOATING HUB MECHANISM:
New. Compatible for drag use
(For Triple Disc Clutch).

FLOATING HUB MECHANISM
This clutch features a floating hub mechanism (patent pending), an advanced evolution of the drive hub system known for its durability and operability. It reduces variations in the engagement point, enhancing performance in competitive settings. With excellent sharpness, it delivers the precise clutch engagement needed for drag competitions.
