Mini-Z MR-015 Replacement Outer Ball Diff Shaft KZ-07B by 3Racing  [KZ-07B]

Outer tuned ball shaft for MR-015

This component is intended for the Kyosho Mini-Z MR-015 platform and supplies the outer tuned ball differential shaft referenced in the product title. It serves as an RC-scale replacement within Mini-Z MR-015 differential assemblies and aids in restoring outer differential action during servicing.

As part of the ball-type differential the outer shaft influences torque flow between left and right outputs and can change the rate of slip during transitions. When tuning, modelers should test diff feel after installing the shaft and tweak other internal parts if required.

Installation involves partial teardown of the MR-015 differential housing to reach the outer shaft and ball components, cleaning mating faces, and careful reassembly to maintain factory clearances. Correct replacement internals help keep the drivetrain smooth and predictable.
