TAMIYA for TT-02 Differential Outer Joint Upgrade - Red Aluminum TT02-13104-RD by Jazrider  [TT02-13104-RD]

Rigid aluminum outer joint for TT-02

This RC-scale aluminum differential outer joint is designed specifically for TAMIYA TT-02 chassis use and carries the model number TT02-13104-RD. The red aluminum outer joint replaces common plastic outer cups to provide a firmer interface at the differential output, helping to reduce flex between the differential and drive shafts during normal hobby operation.

Installation is a routine differential service operation: remove the differential housing, withdraw the stock outer joint, fit the aluminum outer joint onto the differential output stub, verify seating and rotational clearance, then reassemble the housing. Check mating surfaces and fasteners for correct fit and torque, and confirm there is no binding across the drive angle before running.

From a tuning perspective this part is a straightforward driveline upgrade: the stiffer material alters feedback and wear patterns at the outer output, so re-check gear mesh and lubrication after fitting and monitor for any play over initial run-in cycles.
