Precision Pins Built for ECS Drive Shafts

The XRAY 305393 ECS Drive Shaft Pin Set is made for hobbyists who need tighter coupling performance in their RC cars. These polished chrome pins measure 2.0 x 8.5mm and are machined for ECS drive shafts, with flat spots that let the setscrew seat more securely and reduce the chance of slippage during use.

How Flat Spots Improve Coupling Security

Round pins can rotate under load, which may loosen the setscrew over time. The flat spots on these pins create a reliable surface for the screw to clamp onto, improving retention and keeping the drivetrain more stable during aggressive running or racing.

Fitment, Finish, and Practical Benefits

  • Compatibility: Suited to a range of RC models that use ECS drive shafts.
  • Durability: Polished chrome finish improves wear resistance.
  • Precision Fit: Hand-ground for consistent sizing and alignment.
  • Set of 2: Two pins supplied for a single installation or 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.

Which RC models usually accept these pins?

These pins fit vehicles that use standard ECS drive shafts, frequently found on many 1/10 scale touring and buggy models. Check shaft diameter and coupling style before fitting.

Do the flat spots require special setscrews?

No special screws are needed. The flat spot simply gives the existing setscrew a better surface to press against, improving grip with standard grub screws.

How should I maintain these pins?

Keep the pins clean and check the setscrew torque periodically. Polished chrome resists corrosion but wiping away dirt and rechecking clamping force will extend service life.
