We proudly introduce the BlackBoost 722.9 Performance Clutch Kit


This Kit contains all necessary clutch elements to cover the 7 speed 722.9 transmission platform. Our Clutch compound has been developed over years of testing on and off track, with the target of creating the perfect link between performance and daily drivability.

It has a much higher coefficient of friction and is capable of resisting higher temperatures compared to OEM clutches. This Kit has been extensively tested on BlackBoost setups some of them handling 1450+nm/wheel even on AWD platforms.

No aftermarket Clutch Kit today is capable of performing in such a scale with those enormous torque numbers without increasing Clutch Pressure over TCU Software calibration. In order to withstand such torque outputs, it is vital to tune the TCU (transmission control unit) to modify limiters and increase clutch pressure.

Smooth shifting and transmitting enormous power were our goal and this is the result;

The perfect Clutch Kit to re-build or upgrade any 722.9 7 speed transmission available for AMG vehicle platforms
