High precision ECS drive shaft pins

RC builders who want tight tolerances will value the XRAY 305394 ECS Drive Shaft Pins. At 2.0 x 9.0mm and finished in polished chrome, these pins include a machined flat spot so the setscrew sits firmly. That flat profile helps reduce slippage and makes routine maintenance faster and more reliable.

Advantages for competitive setups

These hand-ground pins deliver consistent sizing for smooth drivetrain alignment. The flat spot is designed so the setscrew nests into the coupling, improving grip under load and helping prevent loosening during hard runs. They are a practical choice for racers and hobbyists who service their cars often.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How do I check the pins fit my couplings?

Measure your existing pin hole and compare to 2.0 x 9.0mm. The polished chrome finish and standard sizing mean these pins usually fit common ECS couplings used in many kits.

Do the flat spots require special setscrews?

No special setscrew is needed. The flat spot gives the setscrew a stable seating point so standard grub screws can lock the pin more securely than on a round surface.

Any tips for installation and maintenance?

Keep mating surfaces clean and use a thread locker rated for small fasteners if you prefer. Check the setscrew torque after a few runs and recheck during routine service.
