Tamiya 54477 - 1/10 RC TT-02 Universal Shaft Cup Joint OP-1477 - Steel cup joint upgrade for 1/10 TT-02 drivetrains  [54477]

Stiffen your TT-02 drivetrain with steel cup joints

The Tamiya 54477 - 1/10 RC TT-02 Universal Shaft Cup Joint OP-1477 provides a straightforward upgrade for TT-02 builders who want a tougher drivetrain. These steel gearbox cup joints replace the standard plastic pieces in the kit to reduce wear under load and improve long term reliability.

Why steel outperforms plastic parts

Plastic cup joints can deform or wear quicker during frequent use or spirited running. Choosing steel cup joints lowers the chance of premature failure, keeps drivetrain tolerances tighter, and cuts down on replacement frequency.

Designed for TT-02 installs

This part is made with the TT-02 platform in mind, so fitting is usually direct when replacing stock components. Whether refreshing an older kit or upgrading a new build, the cup joints are intended to integrate cleanly with the TT-02 universal shaft assembly.
