Make the TB-03D more predictable with Tamiya 54125

The Tamiya 54125 Direct Coupling links the rear left and right wheels on TB-03D chassis to increase stability when traction is limited. Placing the centre pulley in direct mode allows the system to apply braking forces to all four wheels more effectively, which helps with heavy braking zones.

Balance for drifting and tight cornering

When the rear tyres are coupled the vehicle gains a smoother, more controllable drift character, enabling drivers to carry speed while negotiating tight lines. This coupling is compatible with TB-03, TB-03D and EVO5 chassis layouts and suits a range of tuning choices.

Yes. The coupling uses cap screws and standard fittings so it can be swapped out when you want to return to an open differential or try alternate setups.
Any linked system changes load distribution slightly. Regular inspection of needle rollers and gears will help spot wear early and keep the drivetrain reliable.
