TAMIYA FF02 M03 M03L M03M M04L M04M Ball Differential Upgrade, Light Blue Anodised - M03M-01/LB by 3Racing  [M03M-01/LB]

Setup-focused aluminium ball differential for TAMIYA chassis

This aluminium ball differential system is a scale RC driveline component compatible with TAMIYA FF02, M03, M03L, M03M, M04L and M04M chassis variants. The finish is light blue anodised aluminium and the component replaces original plastic or steel diff housings in applications where a ball differential is specified.

Performance notes: the unit delivers a precision seating surface for diff balls and supports progressive tuning via shim stacks and clutch adjustments customary to TAMIYA ball diffs. It integrates into the OEM differential assembly and does not require modifications to motor, gearbox or electronic components.

Assembly guidance: ensure correct alignment with factory diff cups and set spur gear mesh accurately, apply thread locking to metal fasteners where appropriate, and avoid excessive torque to prevent bearing preload. Service intervals should include cleaning gear teeth and bearings and inspecting ball and race surfaces for signs of wear.
