This silver anodised aluminium rear universal shaft is engineered as a direct replacement for the Kyosho Mini Inferno ST rear drivetrain. Machined to tight tolerances, it provides a stiffer metal alternative to the standard plastic shaft for improved repeatable engagement under testing and track use.
Installation follows standard small-scale drivetrain procedures: remove the rear assembly or driveshaft retaining hardware, install the aluminium unit in place of the original, and secure using the original fasteners. Ensure correct alignment and runout checks to prevent binding in the differential or gearbox during high RPM or load conditions.
Intended for hobbyists focused on consistent mechanical performance, the shaft reduces wear at the rear connection and improves mounting stiffness during suspension and gearing trials. It does not modify gearing ratios or electronics and should be treated as a precision mechanical replacement on compatible Mini Inferno ST models.
