Fine Tuned Pins for ECS Drive Shafts

The XRAY 305393 ECS Drive Shaft Pin Set replaces standard pins with polished chrome 2.0 x 8.5mm pins that feature a machined flat. This flat lets the setscrew clamp more reliably into the coupling, cutting down on movement and loosening during use.

Flat Spot Design Advantages

A small flat on the pin provides a positive seating area for the setscrew rather than a rounded contact. That translates to better retention under torque and smoother power transfer through the drivetrain.

Compatibility and Key Details

  • Compatibility: Intended for RC models that use ECS drive shafts and matching couplings.
  • Material: Polished chrome offers good resistance to wear and surface damage.
  • Precision: Ground to ensure consistent 2.0 x 8.5mm sizing.
  • Package: Supplied as a pair for immediate fitting or to keep as spares.
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 suit a touring car chassis?

They will suit touring car designs that use ECS drive shafts with 2.0 x 8.5mm pins. Verify coupling bore and shaft size on your chassis before fitting.

Do flat spots change how the pin wears?

The flat concentrates contact where the setscrew clamps, which can reduce rotational wear. Regular inspection will still help catch any loosening or wear early.

Are replacement pins hard to source?

XRAY parts like the 305393 are widely available through RC retailers. Keep a spare set on hand to minimise downtime when running or racing.
