Mini-Z MR-03 Outer Differential Join for Kyosho - AWD-15/HD by 3Racing  [AWD-15/HD]

Mini-Z MR-03 Outer Differential Reinforcement

This precision aftermarket outer differential join is made for Kyosho Mini-Z AWD layouts and carries the part number AWD-15/HD. It is supplied as a reinforced replacement to improve the durability where the outer join meets the differential housing on Mini-Z AWD assemblies.

Intended fitment covers Mini-Z MR-03 AWD configurations and comparable Mini-Z AWD setups. Installation involves disassembling the front or rear differential housing using standard hobby tools; check gear orientation and mesh carefully during reassembly to prevent premature wear. This component replaces the OEM outer join and is designed to integrate with the existing differential internals.

For tuning and frequent track use the heavy-duty outer join reduces slop at the outer interface and helps preserve gear engagement under higher torque loads, while leaving internal gear ratios unchanged for predictable handling.
