HUDY 106070 Extra Hard Drive Pins 3x10 (4 Pieces)  [HSP-106070]

Extra hard 3x10 pins to extend pin life

This HUDY pack supplies four 3x10 replacement drive shaft pins built for use in RC driveline assemblies. The pins act as standard spare items for models that specify a 3x10 size and are suitable when a firmer pin is desired for setup changes.

"Extra Hard" indicates an increased hardness treatment to limit deformation and resist wear under shear loads in drive cups, dogbones, or cross-pins. These pins are intended for model-scale use only and must not be used in full-scale applications.

To install, extract the worn pin, align drive components, and press the replacement 3x10 pin into place with suitable model pliers or a pin driver. Confirm clearances near hex screws and bearings before completing assembly. Slight differences in pin fit can influence driveline feel, so check seating and retorque fasteners after a brief run.

Use this HUDY 106070 set when replacing worn pins or when a harder pin is wanted for firmer driveline control; always check size and compatibility with your model before fitting.
