TAMIYA TT01 Alloy middle shaft joint set by JAZRIDER JR-CTM-TT01-005  [JR-CTM-TT01-005]

Alloy middle shaft joint for TT-01

This alloy middle shaft joint set is an RC-scale replacement part designed to fit the Tamiya TT01 / TT-01 chassis. Machined from aluminum alloy and finished in blue, the component serves as the mechanical link in the central drivetrain where the middle shaft couples with surrounding gear and drive elements.

Compatibility is limited to the TT01 / TT-01 family as stated, so confirm your chassis code before purchase. The part is intended as a direct replacement for the stock middle shaft joint assembly and is used where the TT-01 layout locates a central coupling between drive components.

Installation is straightforward at a component level: remove the original middle joint from the TT-01 drivetrain, fit the alloy joint into the same interface, and verify alignment and free rotation of the middle shaft and adjacent gears. After installation, check clearance and smooth engagement across the drivetrain under rotation to avoid binding.

In tuning terms, this alloy joint functions as a drivetrain component that can reduce flex at the coupling point compared to typical plastic parts, affecting feel and consistency under load depending on the rest of the drivetrain and suspension setup. Use it as part of measured adjustments to gearbox alignment and shaft runout rather than as a standalone solution.
