Abstract: A collapsible torque transfer shaft arrangement for a motor vehicle powertrain is provided. The collapsible shaft arrangement includes an axially translatable coupling mechanism that allows drive line drive shaft members to telescopically collapse while maintaining a non-rotateable connection among the respective drive shaft members. The coupling mechanism also includes a locking pin arranged in the coupling mechanism such that axial connectivity of the respective drive shaft members is maintained below a predetermined force threshold irrespective of other drive line power train components.
