If you want to tighten up the drivetrain on a Tamiya TT-02, the JAZRIDER black aluminum main shaft is a straightforward upgrade. Replacing the stock plastic shaft reduces flex and gives a firmer response when you push the car on smooth surfaces.
The machined aluminum shaft resists wear and keeps alignment under load, giving a more stable power transfer than the original plastic part. That reduced flex helps the car feel more predictable through acceleration and corner exits.
Made to match the TT-02 mounting points, this main shaft installs without extra trimming or modification, so you can get back to running quickly after the swap.
