TRF 416 Aluminium Ball Differential 416-10 by 3Racing  [416-10]

Technical aluminium ball differential for TRF 416

This aluminium ball differential is produced as a rebuildable, performance-oriented internal unit for Tamiya TRF 416 on-road chassis that require a ball-type differential. It is intended for tuners who adjust ball preload and lubricant viscosity to refine drive characteristics rather than using sealed gear assemblies.

Compatibility is limited to vehicles that conform to the TRF 416 differential pattern. Verify chassis parts lists and housing dimensions prior to installation to ensure correct alignment of internal diff components. This item is for electric on-road applications only.

Service and installation should follow established differential procedures: remove the transmission housing, extract the existing diff assembly, transfer or replace internal elements as necessary, and reassemble with correct shim stacks and torque values. Careful torque control on small fasteners is essential to prevent case distortion and ensure consistent preload settings.

For setup, vary ball preload and experiment with diff fluid viscosities to achieve desired traction and steering response. Inspect balls and race surfaces regularly and clean internal components before re-lubrication to maintain repeatable engagement and limit premature wear.
