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

Built for lasting service on TT-02

This precision aluminum differential outer joint fits TAMIYA TT-02 differentials and is identified as TT02-13104-RD. Replacing the stock plastic outer cup with this red aluminum part reduces deformation at the differential output and helps resist wear during regular hobby use.

Fitting the part is a standard differential maintenance job: open the differential, remove the original outer cup, press the aluminum outer joint onto the output stub ensuring full seating, check rotation and clearance, then close and secure the housing. Inspect screw torque and mating surfaces as part of the reassembly checklist.

For long-term care this upgrade shifts contact stresses and can slow wear on the outer interface; follow normal lubrication and run-in checks and periodically verify there is no developing play after several sorties.
