KYOSHO Mini Inferno ST Front Universal Shaft - Heavy Duty by 3Racing MIF-ST01/HD  [MIF-ST01/HD]

Front Universal Shaft Details

This front universal shaft is produced by 3Racing for use with the Kyosho Mini Inferno ST front driveline as a heavy duty replacement part. It is intended as an RC-scale component to restore or strengthen front drive connection where the original shaft is worn or where a heavier duty option is required for more consistent power transfer on track.

Design focus: compatibility with the Mini Inferno ST front driveline, robust joint geometry to reduce slop, and serviceable wear points for routine inspection. The part acts as a direct-drive link between the gearbox output and the front hubs in the Mini Inferno ST layout, so it affects steering feel and traction under load.

Installation notes: the shaft is intended to be swapped into the stock front driveline location without chassis modification. Check existing dogbones, cups, and hub interfaces for wear before fitment, and inspect set screws or retaining pins after initial runs to confirm secure seating. Regular inspection of the universal joints helps extend service life.

Tuning role: fitting a heavier duty front universal can reduce drivetrain deflection under high load, which may yield steadier steering inputs and more predictable traction during aggressive acceleration or braking. Use it as part of a balanced drivetrain upgrade, not as a substitute for proper drivetrain geometry and suspension setup.
