Upgrade for TAMIYA TT-02: Aluminium Main Shaft with Steel Joint - TT02-13100_13115-LB by Jazrider  [TT02-13100_13115-LB]

TT-02 Main Shaft Replacement

The TT02-13100_13115-LB replacement main shaft assembly is specified for the TAMIYA TT-02 1/10 scale chassis as an aftermarket drivetrain upgrade. The design combines an aluminium main shaft with a steel joint to lower wear at the shaft interfaces and to provide a firmer connection compared with the stock plastic parts.

As a reinforcement inside the gearbox area, this component helps stabilise the drivetrain under higher torque or more demanding driving conditions. The product is supplied in light blue and intended for scale radio-controlled use only.

Fitting is a direct swap of the TT-02 main shaft and joint; the focus is on fitment and drivetrain alignment rather than altering gear ratios, so the tangible benefits are in improved durability and reduced flex. Always inspect adjoining surfaces and fasteners when carrying out the replacement to ensure correct seating.
