TAMIYA TT-01 Middle Shaft Joint - Precision Aluminum JR-CTM-TT01-005 by Jazrider  [JR-CTM-TT01-005]

Precision aluminium middle joint for TT-01

This alloy middle shaft joint set fits the Tamiya TT01 / TT-01 chassis as an RC-scale replacement component. Machined from aluminum alloy with a blue finish, the piece functions as the central coupling between the middle shaft and surrounding drive gears.

Compatibility is confined to the TT01 / TT-01 family; verify your chassis designation prior to purchase. It is supplied as a direct substitute for the original middle shaft joint assembly on TT-01 layouts.

To install: remove the OEM middle joint, fit the alloy joint into the same mounting interface, and check that the middle shaft and adjacent gears rotate freely and remain correctly aligned. After fitting, check clearances under rotation to avoid premature wear or binding.

In tuning terms, replacing a plastic joint with aluminum can decrease flex at the coupling point and tighten drivetrain response. Expect these changes to interact with other drivetrain and suspension settings rather than acting in isolation.
