Today we are showing you more products we are developing for the Porsche PDK gearbox specifically the TURBO PLATFORM. Over the last 6 years we have observed these two failures only found in the high torque Turbo models.

Failure one - The pinion nut is self loosening from the force being applied from the helical cut gear.

Failure two - The mid bearing plate aluminum fastener is stretching and self loosening.

New product release!

Porsche PDK shaft seals. These seals are internal of the dual clutch gearbox. They are responsible for keeping the gear oil on one side and the clutch oil on the other. When one or both leaks you will experience fluid externally via a hollow Allen head bolt.

Speed Density is committed to investing into the PDK found in Porsche 911's and Boxster/Cayman platforms.
