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

Aluminum main shaft for TT-02

This JAZRIDER TT02-13100_13115-LB replacement main shaft assembly is designed for the Tamiya TT-02 1/10 scale chassis as a direct RC drivetrain upgrade. The core components combine an aluminum main shaft with a steel joint to reduce wear where the shaft interfaces with drive components and to provide a stiffer connection compared with typical stock plastic parts.

In practical use the part serves as a low-cost reinforcement inside the gearbox area of a TT-02 scale model, helping to stabilise the drivetrain under higher load from more aggressive throttle or upgraded motor setups. The product is presented in light blue and intended only for scale RC applications.

Installation is a direct swap for the TT-02 main shaft assembly, replacing the original shaft and joint. The design focuses on fitment and drivetrain alignment rather than changing gear ratios, so tuning effects are limited to improved durability and reduced flex under load. Inspect mating surfaces and existing fasteners during replacement to ensure proper seating and alignment.
