HUDY 106071 Replacement Drive Shaft Pins 3x11 Extra Hard  [HSP-106071]

Replacement 3x11 drive pins explained

This HUDY 106071 kit delivers four 3x11 replacement drive shaft pins intended for RC-scale drive trains, featuring the Extra Hard material classification listed by the manufacturer. The set is offered as 4 pcs to serve as spares for any drive shaft design that accepts 3x11 pins.

To install, each pin seats into the matching 3 mm bore and 11 mm length slot on the shaft and should be secured by the vehicle's original retention method. Perform fitting on a flat bench, check dimensions before final assembly, and swap worn pins in matched groups to retain balanced drivetrain behaviour.

When tuning or maintaining a model these pins are consumable parts affecting play and alignment; opting for the Extra Hard version helps keep pin geometry under increased loads from aggressive driving or track conditions.

The HUDY 106071 pack is a compact spare option for RC drive trains that use 3x11 pins, suitable for maintenance and tuning when harder matched pins are desirable.
