Clutch buttons are the friction segments bonded or riveted to a clutch disc to transfer drive and manage heat during engagement. KBC manufactures and wholesales clutch buttons for everything from standard rebuilds through to performance and severe duty builds.

When to use clutch buttons

Where a full organic facing would glaze or burn under repeated heavy engagement, buttons handle the heat better and give a firmer, more positive take-up. That makes them the standard choice on heavy duty and performance clutch builds, and a common upgrade on vehicles working harder than the original clutch was specified for.

Typical applications:

• Heavy duty truck and bus clutch rebuilds
• Performance and motorsport clutch builds
• Agricultural and off-road machinery
• Severe duty commercial applications
• Vehicles operating under sustained high load

Frequently asked questions

Clutch buttons or full facings, which should I use?

Full facings give smoother engagement and are right for most standard applications. Buttons handle heat better and give firmer take-up, which suits heavy duty and performance builds. Tell us the application and we will advise.

Do you supply the rivets as well?

Yes. We stock clutch rivets in the sizes and materials that suit our buttons, plus the tooling to fit them.
