Clutch plates

Full-Circle / 6-rivet Metallic Clutch Discs
Standard disc that is suitable for most applications. Six friction pads provide maximum surface area for low wear rate and high heat capacity.
Available for 7.25" and 5.5" clutches.
In the part number, these disc packs are designated by a “2” for 7.25" clutches and a “9” for 5.5" clutches.

Full-Circle / 8-rivet Metallic Clutch Discs
Same as Full-Circle/6-rivet disc except hubs are attached with 8-rivets on a larger BCD for additional attachment strength for the most demanding applications.
Available for 7.25" clutches.
In the part number, these disc packs are designated by a “4”.

4-Paddle Metallic Clutch Discs
Lower inertia than full-circle discs, but have a slightly higher wear rate.
The smooth radius between the friction segments also lowers core plate stress caused by misalignment between the engine & transmission and/or engine harmonics, minimizing core plate cracking.
7.25" discs feature an 8-rivet hub and 5.5" discs feature a 6-rivet hub.
In the part number, these disc packs are designated by a “3”.
