HUDY 106073 - Replacement Drive Shaft Pins 3x13 Extra Hard (4 pcs)  [HSP-106073]

Replacement Drive Shaft Pins 3x13

This is a set of replacement drive shaft pins sized 3x13 supplied as four pcs, specified as Extra Hard. The pins are intended for scale R/C drivetrains where small-diameter retaining pins secure drive shafts, dogbones, or similar couplings.

Use notes: confirm pin fit in the drive shaft and mating hub before final assembly, inspect for burrs and proper seating, and replace any bent or worn pins rather than reusing damaged parts. These pins serve a retention role in the drivetrain and can affect engagement reliability and service intervals when doing setup or tuning.

The HUDY 106073 pin set is a compact hop-up for maintaining secure drivetrain connections during setup and tuning of scale electric R/C models, offering a harder pin option for improved wear resistance.
