Performance-oriented 7075 diff shaft for TB-03

This 7075 aluminium differential shaft is produced as a direct replacement for the Tamiya TB-03 differential assembly, intended for precision maintenance and reliable service life. The shaft maintains original fitment and alignment while offering the dimensional stability expected from a machined 7075 aluminium component.

Service procedure notes: remove the differential housing, assess gear and bearing condition, then install the shaft ensuring precise engagement with the differential internals. Reassemble in the reverse sequence and verify smooth rotation and correct bearing seating before reintroducing the model to high load running.

In a competitive setup workflow this shaft is suitable for repeatable maintenance cycles and incremental drivetrain tuning that retains geometry while reducing variability from worn stock parts. Use it for planned spares, controlled adjustments, and reliable drivetrain behaviour on TB-03 race or club builds.

Will this shaft alter diff geometry in tuned TB-03 cars?

No. The part is designed to replicate stock dimensions so geometry remains unchanged; it reduces variability caused by worn or deformed original shafts.

Recommended inspection steps during fitment?

Inspect gear face runout and bearing fit, ensure endplay is within expected limits, and confirm the shaft seats without lateral movement before final assembly.

Is this suitable for regular track use or heavy practice sessions?

Yes. The shaft is intended for routine servicing and track use where you require stable dimensional performance; always verify surrounding driveline components for wear to avoid secondary failures.
