Stiffer Drivetrain with XRAY 305391

The XRAY ECS Drive Shaft Pin 1.5 x 9mm delivers a straightforward upgrade for RC builders who want tighter fits and fewer mid-run issues. This two-piece set features carefully hand-ground flat spots so setscrews can bite more reliably, helping to prevent the pins from backing out under load.

Best Uses and Fitment

These drive shaft pins are suited to maintaining a positive mechanical link in your vehicle's drive system. The flats give setscrews a predictable seating surface, which reduces movement and helps stabilise the drivetrain during hard acceleration or rough running. They work well both for club-level racing and weekend trail sessions.
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 XRAY 305391 fit all ECS drive shafts that use 1.5 x 9mm pins?

These pins are made to the 1.5 x 9mm dimension and should fit ECS drive shafts that specify that size. Always verify your shaft diameter and length before fitting.

How should I install the pins for the most secure hold?

Align the flat spot under the setscrew, tighten the screw evenly, and avoid over-torquing. Use a thread locker only if compatible with your setscrew material and maintenance plan.

Do the flat spots affect strength of the pin?

The hand-ground flats are small and intended to improve clamping rather than weaken the pin. They provide a better contact area for the setscrew while maintaining the part's integrity for normal RC use.
