TRF 416 Compatible Aluminium Ball Diff 416-10 by 3Racing  [416-10]

Aluminium ball diff for TRF 416 fitment

This aluminium ball differential is supplied as a drop-in option for Tamiya TRF 416 on-road chassis that call for a ball-type diff. It gives tuners a rebuildable internal unit so preload and lubricant choices control the feel rather than a sealed gearset.

Compatibility is confined to vehicles using the TRF 416 differential pattern. Confirm your chassis parts list and case dimensions before ordering to ensure the internal diff element and housing are compatible. This part is for electric on-road RC use only.

Fitting follows standard diff service practice: open the transmission housing, remove the current diff assembly, swap or replace internals as required, and reassemble with proper shims and torque. Care is required with aluminium housings to avoid stripping the small screw threads or over-tightening.

Tuning and servicing are typical for ball diffs: vary ball preload, experiment with diff fluid viscosity, and routinely check balls and races for wear to refine traction and turn-in. Regular cleaning and lubrication keeps engagement consistent and reduces premature wear.
