TAMIYA TT-01 Alloy Middle Shaft Joint Set JR-CTM-TT01-005 by Jazrider  [JR-CTM-TT01-005]

Aluminum middle shaft joint for TT-01 drivetrain

This alloy middle shaft joint set is a 1/10 scale replacement part made to fit the Tamiya TT01 / TT-01 chassis. Machined from aluminum alloy and finished in blue, the component links the centre shaft to surrounding gears and drive elements.

Compatibility is restricted to the TT01 / TT-01 family as noted, so verify your chassis code before purchasing. The part is engineered as a direct replacement for the standard middle shaft joint assembly found on the TT-01 layout.

Installation at the component level is straightforward: remove the stock middle joint from the TT-01 drivetrain, insert the alloy joint into the same interface, then check alignment and free rotation of the middle shaft and adjacent gears. After fitting, inspect clearance and smooth engagement under rotation to prevent binding.

From a tuning perspective, this aluminum joint can reduce play at the coupling compared with common plastic parts, which may change drivetrain feel and consistency under load depending on the rest of your drivetrain and suspension setup. Use it as one element in measured gearbox alignment and shaft runout adjustments.
