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

Drive shaft pin spare set

This HUDY set provides four replacement drive shaft pins sized 2.5x10 intended for RC-scale drivetrains. The pins are specified as "Extra Hard" which affects how they behave under shear loads and during repeated pit-side swaps. They are a straightforward service item for maintaining retention of dogbones or drive shafts where 2.5mm pins are used.

Fitment and function are simple: verify the pin diameter and length match the existing shaft pin grooves before installation, press the pin into the shaft or cup as required, and check for free rotation and correct axial play after assembly. Because the pins are harder than standard pins, expect increased shear resistance and slightly higher bearing surfaces contact; inspect mating parts for signs of wear when switching from softer pins.

For tuning and maintenance, keep a spare set on the bench to test different failover behaviours during setup changes. Use these pins as direct replacements where the 2.5x10 dimension is required; do not modify or force-fit pins into undersized holes.

Use as direct replacements in compatible 2.5x10 pin housings to restore secure drivetrain retention and test different failure characteristics during setup.
