The 3RACING 416-10C Differential Spring provides a targeted way to smooth power delivery in the Tamiya TRF 416, reducing sudden slip and allowing you to place the car more accurately through complex corners.
This spring is matched to the TRF 416 differential arrangement to help preserve consistent preload and reduce handling surprises during acceleration. It suits drivers seeking subtle, controllable changes rather than radical modifications.
Installation requires only basic tools: replace the factory spring with the 3RACING 416-10C, reassemble the diff and run a few laps to confirm behaviour. Periodic checks of the diff internals will keep performance predictable.
