HUDY 106059 2x10 Extra Hard Replacement Drive Shaft Pins, 4 pcs  [HSP-106059]

Replacement drive shaft pins — HUDY 106059 overview

This HUDY replacement set provides four 2x10 drive shaft pins made for RC-scale drive shafts. The pins are marked "Extra Hard" to denote a harder heat-treated finish versus standard pins, and they perform a simple mechanical role: locate and retain a drive shaft within a hub or coupling to minimise axial movement.

Installation follows standard retention-pin practice: align the shaft hole and push the pin in until it sits flush. To remove or service, use small pliers or a 2 mm pin punch and inspect the fit after reassembly to confirm there is no unwanted play. These small parts play a key part in drivetrain maintenance and tuning by keeping shaft alignment consistent during runs.

Replace worn retention pins or fit these harder pins where deformation under repeated assembly has been a problem to improve long term shaft seating.
