HUDY 106060 Replacement 2.5x10 Drive Shaft Pins Extra Hard 4pcs  [HSP-106060]

Pin set description and purpose

The HUDY 106060 package contains four Extra Hard drive shaft pins of size 2.5x10 for RC drivetrains. The increased hardness affects shear resistance and wear patterns, serving as a simple replacement part for systems using 2.5mm pins.

Check that the 2.5mm diameter and 10mm length match your existing shaft groove before installation. Press the pin into the shaft or cup with even pressure, then confirm free rotation and correct axial play once fitted. Because of the higher hardness, these pins typically resist shearing better but may change how mating components wear.

Retain a spare set on the bench to trial different failure characteristics and to perform routine replacements. Only use these pins where the 2.5x10 dimension is specified and avoid forcing pins into holes that are too small.

Use as direct replacements in compatible 2.5x10 housings to restore secure drivetrain retention and to observe different failure behaviors during setup changes.
