Engineered ECS drive shaft pins for accurate alignment

The XRAY 305394 ECS Drive Shaft Pins are precision machined at 2.0 x 9.0mm and finished in polished chrome. The machined flat spot ensures the setscrew bears on a flat surface, helping to limit movement and maintain alignment over repeated runs.

Why these pins matter for setup and upkeep

Hand-ground for consistent diameter, these pins support smoother drivetrain operation and easier maintenance. The flat spot provides a positive stop for the setscrew inside couplings, reducing the need for frequent retightening in demanding conditions.
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 competitive circuits?

Yes, the precise sizing and flat spot make them suitable for competitive use where consistent drivetrain behaviour matters. Regular inspection is still recommended between events.

How tight should the setscrew be?

Use enough torque to seat the setscrew against the flat spot without over tightening. Check the manufacturers guidelines for your setscrew and coupling to avoid thread damage.

Can these be used in wet or dusty conditions?

The polished chrome finish resists normal corrosion, but cleaning and inspection after wet or dirty runs will keep components working longer and prevent buildup that can affect fit.
