Secure Fit with XRAY ECS Drive Shaft Pins

For RC hobbyists focused on reliability, the XRAY 305390 ECS Drive Shaft Pins are a sensible choice. At 1.5 x 8.5mm these pins are machined for a snug fit in compatible drive shaft assemblies.

Polished Finish and Flat Spots for Solid Retention

The pins are polished and include flat spots so the setscrew can seat firmly, reducing the chance of the pin shifting under load. This design detail helps keep the ECS drive shaft assembly stable during aggressive runs.

Two Pins Supplied for Immediate Use or Spares

Whether doing routine upkeep or replacing worn parts, the two-pin pack gives you a quick swap option or spare set for future maintenance, helping preserve consistent drivetrain performance.
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 drive shafts?

Check the shaft bore and pin diameter on older parts against the 1.5 x 8.5mm size to confirm fit, as some legacy shafts use different pin specs.

How should I install the pins to avoid loosening?

Make sure the flat spot aligns with the setscrew and tighten the setscrew to the recommended torque for your drive shaft to maintain secure seating.

Are these pins suitable for high-torque setups?

They provide reliable retention for many setups, but confirm compatibility with your drivetrain and consider hardened or upgraded parts if you run extreme power.
