    The most common truck clutch discs (used in the vast majority of OEM clutches) are called full-face organic discs. That means it's made of a fairly thick organic friction material that sits in a full ring or circle on the clutch disc. The two main reasons why this type of disc is so widely used are, firstly, the organic friction material offers a lot of options in terms of friction characteristics that can be adjusted to maintain a given torque, and because the friction material is a complete ring, it has A very easy to control linear engagement.

    Another common friction material is ceramic. Ceramics grip the flywheel and pressure plate better than organic materials, so it is fairly common for ceramic materials to break down into small areas on the clutch disc. These areas are called "discs" and most ceramic clutch discs are 3, 4, or 6 discs.

    An important property of ceramic clutch discs is that they do not slip like organic discs. In general, ceramic clutches have only a small fraction of the clutch travel where the clutch slips, and anywhere else the clutch pedal travels, the clutch is either fully engaged or fully disengaged. You can think of a ceramic clutch as an on/off switch compared to an organic clutch that functions more like a dimmer.

    The advantage of the ceramic clutch disc is that this quick engagement makes the clutch feel very responsive as you switch gears as you move. But it also does make it harder for the car to move from a stop. This is especially true for all-wheel-drive cars.

    Another friction material that is now increasingly common in clutches is Kevlar. The best way to think about a Kevlar clutch is that it's somewhere between organic material and ceramic material. It grips better than an organic one but lasts longer than a ceramic clutch.
