TAMIYA TT-02 Aluminum Differential Outer Joint (Red) by JAZRIDER TT02-13104-RD  [TT02-13104-RD]

Aluminum outer joint for TT-02

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

Installation is a basic differential service task: 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. Inspect mating surfaces and fasteners for proper fit and torque, and confirm there is no binding across the drive angle before running.

In tuning terms this part serves as a straightforward driveline upgrade: its stiffer material changes the feedback and wear characteristics at the outer output, so check gear mesh and lubrication after installation and monitor for play over initial run-in cycles.
