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

Aluminum ball differential compatible with TRF 416

This aluminum ball differential is a direct replacement for Tamiya TRF 416 on-road cars that specify a ball-type diff. It provides a serviceable internal assembly so builders can tune preload and lube rather than swapping a sealed gear unit.

Use only on vehicles that match the TRF 416 differential format. Verify your chassis parts list and housing dimensions before purchase to be sure the internal diff element and case match the TRF 416 standard. This component is intended for electric on-road RC models only.

Installation follows common differential service steps: remove the transmission housing, extract the installed diff, transfer or replace internal parts as needed, then reassemble with correct shims and torque. Treat the aluminium housing like any metal hop-up and avoid over-tightening the small hex screws during reassembly.

Tuning and upkeep are standard for ball diffs: adjust ball preload, try different diff lube viscosities, and inspect balls and races for wear to tune traction and steering response. Regular cleaning and relubrication will keep engagement predictable and extend service life.
