Tamiya 22103 44mm LW Swing Shaft Pair for 1/10 Shaft-Driven Cars  [22103]

Direct-fit shafts for shaft-driven touring cars

Provided as a matched pair, these 44mm lightweight swing shafts suit 1/10 scale shaft-driven touring models and TRF-type chassis. Their lower mass lowers rotating inertia while keeping dimensions compatible with standard swing-shaft assemblies.

They are normally fitted at the differential to hub connection on shaft-driven layouts. Confirm the required 44mm length and coupling interface for your chassis before fitting as these parts are intended for direct replacement where specified.

Checklist for correct installation

• Check shaft straightness and ensure free rotation before assembly to prevent drivetrain vibration.
• Confirm that couplings and set screws are correctly located and tightened to prevent loosening under load.
• Apply a small amount of suitable lubricant to splines to reduce wear but avoid excess that attracts debris.
• Conduct a low-speed run to verify smooth operation before normal use.

Role in servicing and fine tuning

These shafts make a practical upgrade or replacement when seeking marginal reductions in rotating mass for crisper throttle response. They also serve as standard service items when diagnosing driveline drag or imbalance.
