Tamiya 54125 TB-03D Direct Coupling Set - Racing Stability  [54125]

Improve TB-03D stability with Tamiya 54125

The Tamiya 54125 Direct Coupling is a precision component that links the left and right rear wheels on the TB-03D chassis. By switching the center pulley to direct mode the assembly delivers improved vehicle balance on slippery or low-traction surfaces, making braking more predictable in race conditions. The direct setup also enables effective four-wheel braking for tracks that demand strong stopping power.

Built for controlled drifting and track work

Linking the rear tyres gives the Tamiya 54125 a more linear response during drifts, producing a smooth, controllable slide for drivers aiming to hold speed through tight corners. The coupling is compatible with TB-03, TB-03D, and EVO5 chassis variants and fits into a variety of tuning setups for both drift and circuit use.
