Kyosho Mini-Z AWD Aluminum Differential Outer Join by 3Racing AWD-15  [AWD-15]

Mini-Z AWD differential outer join

This is an RC-scale aluminum differential outer join designed for Kyosho Mini-Z AWD chassis, supplied by 3Racing as part number AWD-15. It functions as an external differential coupling intended for use on MR-03 AWD style drivetrains where the outer join is serviceable or replaceable.

The part is made from aluminum alloy to offer greater wear resistance compared with common plastic outer joins, and it’s intended to affect the mechanical coupling and longevity of the differential assembly rather than change electronic components like ESC, Motor, or Servo. Use this as a replacement or light hop-up when refurbishing an aging Mini-Z AWD differential or when tuning differential feel.

Installation typically requires access to the differential housing on the Mini-Z AWD platform and basic RC tools such as a Hex Driver. When replacing the outer join, inspect surrounding splines and bearings for wear and reassemble with proper shimming to preserve gear mesh and differential action. This part is intended for hobby and track-scale RC car maintenance and tuning only.
