This aluminium middle shaft joint set is made for the Tamiya TT01 / TT-01 chassis and acts as a direct replacement for the stock middle joint assembly. Machined from aluminium and finished in blue, it connects the centre shaft to surrounding drive gears.
It is intended specifically for the TT01 / TT-01 family; confirm your chassis code before purchasing. The part replaces the factory middle joint at the central coupling point in the TT-01 drivetrain layout.
Installation involves removing the original middle joint, fitting the alloy joint into the same interface, and verifying that the middle shaft and adjacent gears rotate freely and sit in proper alignment. After assembly, inspect running clearance to prevent binding.
In practical tuning terms, the aluminium joint can reduce coupling flex versus plastic, affecting drivetrain feel and load transfer. Assess this upgrade alongside gearbox alignment and bearing condition for best results.
