Upgrade ECS Couplings with Accurate Pins

The XRAY 305393 ECS Drive Shaft Pin Set offers a precise replacement for worn or loose drive shaft pins. These polished chrome pins are sized at 2.0 x 8.5mm and include flat spots so the setscrew can clamp more positively into the coupling.

Benefits of a Flattened Contact

When the pin has a flat face the setscrew can press into a defined area rather than sliding on a round surface. That reduces movement under load and helps maintain alignment and drivetrain efficiency during spirited running.

Where These Pins Shine

  • Compatibility: Works with many RC kits that use ECS drive shafts.
  • Wear Resistance: Polished chrome finish for longer life.
  • Accurate Size: Ground to tight tolerances for dependable fit.
  • Pack Quantity: Supplied as a pair for installation or spare use.
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.

Will these pins fit older ECS couplings?

They will fit older couplings that accept 2.0 x 8.5mm pins, though you should verify shaft and bore sizes on vintage parts before ordering.

Can I reuse an existing pin with a flat spot?

If the existing pin is in good condition and the flat is intact it can be reused, but replacing with a new XRAY 305393 pin ensures precise contact and consistent clamping.

Is installation difficult for beginners?

Installation is straightforward: remove the coupling setscrew, slide out the old pin, insert the new pin with the flat positioned for the setscrew, then torque the screw to spec.
