These high performance clutch plates from Sachs are a direct replacement for an OEM clutch plate and have a much more aggressive friction surface which allows them to handle up to 80% more torque. This makes them ideal for competition cars where a more aggressive clutch actuation is acceptable. For these clutch plates to operate at their maximum torque capacity they should be used with a Sachs high performance clutch cover.

|
Reinforced material |
Asbestos free composite raw material OE approved |
|
Stainless steel ring (AISI304) |
Separate stainless steel rings assure maximum sealing around cylinder bore also on NOS and/or turbo charged engine where boost is over 2 bars. No head and block machining required |
|
Silicon beading |
Silicon-based beading is applied on critical areas to improve sealing around all cooling water and oil passages |
