*Definition:
DAMPENED
The center drive hub is not mounted solid to the solid steel plate. Most commonly you will see a spring-loaded assembly.
CUSHIONED
The clutch lining/steel plate will have some type of link to absorb the shock load. Most commonly you will see extra rivets and links between the ID of the facings and the OD on the drive plate. Not one solid steel plate.
BUTTON
The most aggressive clutch material is the bronze, metallic button. It offers extended life using reduced static pressures and a quick, clean engagement.
