A compact pack of four replacement drive shaft pins sized 3x14, specified by HUDY as extra hard. These pins are intended as scale RC drivetrain spare parts to restore worn pin connections or to provide a firmer fit where standard pins have shown deformation under load.
The pack focuses on the mechanical role of a drive pin: securing drive shaft joints and transferring torque across couplings. The extra hard treatment reduces wear and the risk of elongated pin bores in aggressive setups, while the 3x14 sizing targets shafts and couplers designed for that nominal pin diameter and length.
Installation notes: verify pin orientation and bore alignment before pressing pins into place, replace pins in matched pairs when possible to keep drivetrain balance, and inspect mating bores for wear that might require reaming or replacement of the mating component.
Use these extra hard 3x14 pins when restoring drivetrain integrity or when aiming for increased pin longevity under higher torque usage; always confirm fitment before final assembly.
