The HUDY 106072 set supplies four extra hard 3x12 drive shaft pins intended for R/C drivetrain use. These parts are produced as direct replacements to hold drive shafts and couplings firmly where increased pin stiffness is needed.
Compatibility advice: they are aimed at general R/C driveshaft assemblies but always verify pin diameter and length against your model before fitting. Replace pins that show wear or bending to maintain a precise driveshaft connection.
A compact spare pack for routine repairs, the HUDY 106072 pins are useful for modellers who require reliable retention hardware for drivetrain maintenance.
