Stiffened Diff Shaft for Tamiya TB-03 Performance

The Tamiya TB-03 Aluminum 7075 Differential Shaft by 3Racing is intended to increase drivetrain robustness while preserving the TB-03 chassis characteristics. The 7075 alloy gives a strong component that copes well with repeated acceleration and braking loads. It suits both weekend club racers and scale hobbyists wanting a dependable replacement shaft.

Why 7075 Works Well in RC Parts

The 7075 grade offers a high strength-to-weight balance that helps the differential resist bending and wear. That translates to steadier power transfer and reduced chance of deformation during more demanding runs.

Easy Swap for TB-03 Owners

Made to align with TB-03 dimensions, the 3Racing TB03-07 replaces stock shafts without major setup changes. Installation is direct and designed to be familiar to anyone experienced with TB-03 maintenance.

Can I use this shaft with aluminium diffs or only stock diffs?

The shaft is compatible with standard TB-03 differential housings; check fit if you run custom or heavily modified aluminium diff assemblies.

Does the TB03-07 affect handling balance?

Because the shaft is lightweight and stiff, drivers may notice crisper drivetrain response but no significant change to chassis balance when fitted correctly.

What routine checks are recommended after installing the shaft?

After initial installation, verify clearances and fastener torque then inspect after a few runs for any unusual wear or loosening.
