Upgraded clutch pack for the 722.9 transmission
This clutch pack contains everything needed to upgrade the 7-speed 722.9 automatic transmission.
Development of the clutch material is based on years of testing in both street and track conditions. The goal has been to combine high performance with excellent everyday drivability.
The friction material has a significantly higher coefficient of friction than the original parts and withstands considerably higher heat loads. The pack has been tested in demanding set-ups where the torque delivered to the wheels has exceeded 1450 Nm, including in all-wheel-drive vehicles.
No aftermarket clutch pack can handle torque levels this high without optimisation of the transmission control unit (TCU) software. To manage high power and torque figures, the torque limits in the TCU software must be adjusted and clutch pressure increased.
The result is very smooth shifting combined with exceptional power transfer capability.
The pack is ideal for rebuilding the 722.9 transmission or improving its performance on all AMG vehicle platforms.
