Tamiya F103GT Replacement Ball Bearing Set F103GT-29 by 3Racing  [F103GT-29]

Replacement ball bearings for the Tamiya F103GT

This ball bearing set is intended as an RC-scale replacement for the Tamiya F103GT chassis, supplying low-friction rolling points where original bearings can wear or increase drivetrain drag. Use the set at drivetrain and wheel hub locations to recover smooth rotation.

Fitting the bearings is a simple maintenance task: remove the old bearings, clean the seating areas, press the new bearings in until they are flush and verify free spin before reassembling components. These bearings support routine checks and selective swaps during setup or after running sessions without altering the chassis.

For tuning, replacing worn bearings with precise, low-friction units helps cut drivetrain losses and stabilise rotational behaviour under load, which can improve lap time consistency and provide a cleaner throttle feel when paired with correct gear mesh and tyre choices.

• Compatibility: made for the Tamiya F103GT chassis only.
• Maintenance notes: watch for play, grit or noise and replace bearings that are compromised.
• Tuning role: reduces rolling resistance at drivetrain and hub points to help consistent power transfer.
