The Tamiya TRF 416 Aluminum Ball Differential by 3Racing (416-10) is an aluminium upgrade created to increase durability and make vehicle behaviour more consistent. It suits drivers who want more reliable traction at racing pace.
This aluminium assembly outperforms plastic stock parts in stiffness and longevity. The improved fit keeps power delivery stable under heavy acceleration and abrupt direction changes.
By reducing unwanted play and flex, this differential supports tighter lines and steadier exits. It is a practical upgrade for club racers chasing more consistent lap times.
