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

Compact replacement for shaft-driven 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 minimise 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.

Installation tips for smooth operation

• Check each shaft for straightness and free spin before fitting to avoid vibration translating through the drivetrain.
• Tighten couplings and set screws to the correct torque and verify engagement depth to prevent slipping under load.
• Apply a light lubricant to splines or mating faces to reduce wear, but avoid over-application that attracts grit.
• Power up the car slowly after fitting and listen for unusual noises before running at full speed.

Use in maintenance and incremental tuning

Being lighter than some stock options, these shafts help reduce rotating mass for crisper throttle response and are useful as scheduled replacement parts. They are also handy when tracing drivetrain drag or imbalance during setup and repairs.
