Tamiya TB-03 Differential Shaft 7075 Aluminium TB03-07 by 3Racing  [TB03-07]

High-strength 7075 shaft for TB-03

This 7075 aluminium differential shaft is made as a direct replacement for owners of the Tamiya TB-03 chassis who need a longer-lasting spare for drivetrain servicing. It is designed to substitute worn factory shafts while keeping correct fitment and alignment in the TB-03 differential unit.

Fitting notes cover orientation and checks: remove the diff carrier, inspect gears and bearings for any wear or damage, then insert the shaft ensuring proper meshing with internal parts. Reassemble in reverse and inspect for free rotation and absence of binding prior to installing the model back into service.

For tuning and maintenance the shaft provides consistent dimensions from machined 7075 aluminium, helping to retain chassis geometry during repairs or incremental drivetrain tweaks on TB-03 setups. It suits routine servicing and parts inventory needs.
