We are please to have available the new hardware in the Pro75 line for CTI motors.
These cases are now one piece and no longer have a piece attached on the thrust end of the case at the factory.
The Forward Closure and the Nozzle Holder are interchangable but the new Retaining Ring and the new Rear Retaining Ring are not. Threads are different.
All parts are now available online from Sunward:
