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

TT-02 Aluminum Main Shaft Upgrade

This TT02-13100_13115-LB replacement main shaft assembly is engineered for the TAMIYA TT-02 1/10 scale chassis as a direct drivetrain upgrade. The assembly pairs an aluminum main shaft with a hardened steel joint to reduce wear where the shaft interfaces with driven components and to give a firmer connection compared with the original plastic parts.

In practical use the part acts as an economical reinforcement inside the gearbox region of a TT-02, helping to stabilize the drivetrain when subjected to stronger motors or more aggressive throttle inputs. The unit is finished in light blue and is intended solely for scale RC applications.

Fitting is a direct swap for the TT-02 main shaft and joint; the design prioritizes correct fitment and drivetrain alignment rather than changing gear ratios, so improvements are primarily in durability and reduced flex. Inspect mating surfaces and existing fasteners during replacement to ensure proper seating and alignment.
