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

Replacement pins for RC drivetrains

This HUDY 106060 set supplies four replacement drive shaft pins sized 2.5x10 for RC-scale drivetrains. The pins are manufactured with an Extra Hard finish, which changes how they respond to shear loads and repeated service swaps. These are a basic service item to maintain retention of dogbones or drive shafts using 2.5mm diameter pins.

Fitment and installation are straightforward: confirm the pin diameter and 10mm length match the existing groove and hole before fitting, press the pin into the shaft or cup as needed, and then check that mating parts rotate freely and axial play is correct. Because these pins are harder than standard pins, expect improved shear resistance and somewhat different contact wear; inspect mating cups and shafts after swapping from softer pins.

For setup and maintenance, keep spares on the workbench to evaluate different failure behavior during tuning. Use these pins only as direct replacements where a 2.5x10 pin is specified; do not modify or force them into undersized holes.

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