Stable Drive Shaft Pins for Tough Use

The XRAY 305393 ECS Drive Shaft Pin Set is designed to give a firmer coupling connection in RC cars that see heavy use. These polished chrome pins are 2.0 x 8.5mm and the hand-ground flat spots let setscrews bite in without the pin turning under load.

Why the Flat Spots Matter On Track

Flat spots reduce the tendency for pins to rotate inside the coupling, which helps keep the drivetrain aligned and minimises loosening. That means more predictable handling and fewer roadside repairs during club nights or track sessions.

Practical Features and Fitment

  • Compatibility: Fits a variety of models using ECS drive shafts.
  • Finish: Polished chrome for corrosion resistance and smooth operation.
  • Tolerance: Ground for accurate dimensions and reliable seating.
  • Contents: Two pins included for installation or 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.

Do I need to change my coupling to use these pins?

No coupling swap is required provided your coupling accepts 2.0 x 8.5mm pins. Simply slide the pin in and secure with the existing setscrew positioned over the flat.

Are these pins suitable for off-road buggies?

Yes, they are suitable for off-road use where drive shafts endure impact and torque, as long as the shaft and coupling dimensions match.

How tight should the setscrew be?

Tighten to a firm feel without overtorqueing; check periodically after running. Proper torque keeps the screw engaged with the flat without damaging the pin.

Can these pins be filed to fit other sizes?

Modifying pins is not recommended as it can affect fit and strength. Use pins sized to the coupling for best results.
