HUDY 106070 Replacement Drive Shaft Pins 3x10 Extra Hard (set of 4)  [HSP-106070]

Replacement drive shaft pins for R/C driveline

This HUDY set supplies four 3x10 replacement drive shaft pins produced for RC-scale driveline assemblies. The parts are intended as direct spare items for general R/C applications where a 3x10 pin is specified, serving as a wear item or a stiffer option when swapping components during a setup session.

The "Extra Hard" designation describes the pin's hardened treatment level used to resist deformation under pin shear and repeated use in drive cups, dogbones, or cross-pins. These pins remain an accessory sized for model use only and are not to be interpreted for any full‑scale vehicle application.

Installation is straightforward: remove the worn pin from the drive assembly, align the drive shaft and cup, then press the replacement 3x10 pin into place with appropriate pin tools or pliers sized for model work. Check clearance around nearby hex screws and bearings before final assembly. When tuning, small differences in pin fit can affect driveline lash and feel, so confirm secure seating and retorque adjoining fasteners after a short test run.

Use this HUDY 106070 set when replacing worn pins or when a harder pin is preferred for tighter driveline control; verify size and fit against your model's drive components before installation.
