| Manual Clutch | Located between the engine and the transmission. The manual clutch transmits rotation from the engine to the drivetrain. Made up of a clutch cover and clutch disc. |
| Clutch Cover | The clutch cover is attached to the flywheel and serves to engage and disengage power via clutch disc. |
| Clutch Disc | The clutch disc is pressed by the clutch cover against the flywheel to transmit rotation. |
| Solid Disc | A clutch disc without torsion springs. |
| Normal Disc | A clutch disc with standard function, for general application. |
| Silent Disc | This product features additional functions to absorb noise and drive-related vibration in order to improve quietness when operating the engine. |
| Organic | A clutch disc made of organic friction materials. |
| Metallic | A clutch disc made of metallic friction materials. |
| Combination Disc | A clutch disc made of a combination of organic and metallic friction materials. |
| WAD | Abbreviation of Wide Angle Damper. A clutch disc equipped with high performance damping and enhanced vibration reduction characteristics to handle engines with high RPM variation, such as diesel and direct fuel injection engines. |
| Diaphragm Spring | The daiphragm spring is located in the clutch cover structure. |
| Pull Type Clutch | A clutch cover designed for high performance vehicles. |
| Peak Cut Clutch | Clutch pedal pressure remains even during clutch disc wear. Clutch pedal pressure normally gets heavier after wear of the clutch disc. |
| Unity Disc | A clutch disc designed with unified parts to reduce the number of components, for cost efficiency. |
| Clutch Set | The clutch set is made of the clutch disc and clutch cover. |
| Snap-in Release Bearing | The snap-in release bearing is an EXEDY patent for the pull type cover release bearing. The bearing can be taken out with a screwdriver. |
| Support parts | The parts fitted to the clutch cover to make the installation easier. There are 3 different types. (set bolts, set wire and set plate) All of them are painted. |
