Kyosho Mini-Z AWD Heavy Duty Differential Outer Join by 3Racing AWD-15/HD  [AWD-15/HD]

Mini-Z AWD Differential Outer Join

This is an RC-scale outer differential join designed for Kyosho Mini-Z AWD models, provided by 3Racing as part number AWD-15/HD. The component serves as a direct replacement or upgrade point for the AWD differential assembly, focusing on increased robustness where the outer join meets the differential housing.

Fitment is intended for Mini-Z MR-03 AWD configurations and similar Mini-Z AWD layouts. Installation requires basic teardown of the rear/front differential housing and standard hobby tools; confirm orientation and mesh before reassembly to avoid premature wear. This part replaces the OEM outer join and is intended to work within the existing differential system of the model.

When used for tuning, the heavy-duty outer join helps maintain gear engagement under higher loads typical of aggressive on-track setups or frequent practice sessions, supporting consistent differential behavior without changing internal gear ratios.
