Tamiya 22103 44mm LW Swing Shaft Pair for 1/10 Drivetrain  [22103]

Compact replacement for shaft-driven RC drivetrains

These 44mm lightweight swing shafts are supplied as a matched pair intended for 1/10 scale shaft-driven touring cars and TRF-type chassis. Their reduced mass helps minimize rotating inertia in the drivetrain while keeping a form factor compatible with common swing-shaft layouts.

Fitment is typically at the differential-to-hub connection on shaft-driven setups. Before installation, confirm shaft length and coupling style on your specific chassis: the part is designed to be a direct physical replacement where 44mm swing shafts are specified.

Practical installation and setup notes

• Inspect shafts for straightness and free rotation before fitting to avoid drivetrain vibration.
• Ensure couplings and set screws are secure and properly seated; check engagement depth to prevent slippage.
• Light lubrication at splines or mating surfaces can reduce wear; avoid excessive grease that may attract debris.
• After installation, perform a slow power-up check to confirm smooth operation before full-speed running.

Maintenance and tuning role

As a lightweight component, these shafts contribute to easier throttle response and reduced rotating mass in incremental tuning setups. They serve as routine replacement parts for maintenance cycles and may be used when diagnosing drivetrain drag or imbalance.
