The Tamiya 51416 RC 52T ball differential is a targeted upgrade for TRF201 chassis owners who want steadier power delivery and improved control. It is also compatible with FF-03 cars, making it useful across multiple Tamiya builds.
The 52-tooth arrangement helps distribute torque more evenly to the driven wheels, cutting down sudden slip and improving traction. That yields more stable corner exits and predictable acceleration.
This gear set is suitable for track use and everyday practice runs. Fit it to TRF201 or FF-03 chassis to benefit from more consistent handling and reduced wheel spin under load.
