Accurate Seating with XRAY 305391 Pins

The XRAY ECS Drive Shaft Pin 1.5 x 9mm provides a precise replacement pin option for hobbyists focused on reliable drivetrain connections. Each pin has hand-ground flat spots so setscrews can secure them more effectively, lowering the likelihood of loosening during use.

Application Notes

These pins maintain a dependable joint in the drive train by offering a stable contact area for the setscrew. That stability helps keep rotational play to a minimum, which is useful whether you are fine-tuning for track days or routine club events.
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.

Are these pins suitable for high torque setups?

They are intended to improve setscrew grip but check your drivetrain layout and torque expectations. For very high torque applications consider complementary upgrades alongside pins.

What is the best way to prevent pin slippage?

Ensure the flat is positioned under the setscrew, use the correct screw length and torque, and inspect after initial runs. Replacement with a matched setscrew can also help.

Is any special tool needed to install them?

Standard hex or screwdriver tools used for your setscrews are sufficient. Use light torque to start and then secure to the recommended tightness for your setup.

Do these pins affect balance or handling?

The pins are small and primarily affect connection reliability rather than balance. Their main benefit is reducing drivetrain play which can indirectly improve predictability of handling.
