Tamiya 54215 - Spur Gear Spacer for F104/TRF101, Setup Upgrade  [54215]

Optimise F104 and TRF101 gear layout with a simple spacer

The Tamiya 54215 Spur Gear Spacer is intended to increase tuning options for F104 and TRF101 chassis. It enables the fitting of touring car spur gears to F103 and F104 models, giving racers a practical means to adjust gear ratios for different circuit demands.

Access more gear ratio combinations for better tuning

Fitting the Tamiya spacer expands the variety of spur gears you can try, helping you refine acceleration, midrange response and top speed to suit smooth or technical track surfaces.

Refine traction through differential configuration

In addition to ratio changes, the spacer can allow an increase in differential ball count when used with compatible parts, which can improve traction and directional stability for confident cornering.
