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

Replacement swing shafts for compact shaft layouts

This matched pair of 44mm lightweight swing shafts is made for 1/10 scale shaft-driven touring models and TRF-style chassis. The lower mass reduces rotating inertia while keeping a profile that fits common swing-shaft assemblies.

Typical fitment is between the differential and wheel hub on shaft-driven cars. Double-check shaft length and coupling form on your chassis before fitting: these parts are intended as direct replacements where 44mm shafts are specified.

Fitting notes to avoid vibration

• Examine shafts for straightness and smooth rotation before assembly to prevent drivetrain wobble.
• Make sure couplings and grub screws are seated correctly and tighten to the recommended level to avoid slippage.
• A light smear of lubricant on splines helps longevity but keep it minimal to reduce dirt pickup.
• After installation run the system at low speed first to confirm everything turns smoothly.

Role in servicing and setup

These lightweight shafts are useful for tuning where small reductions in rotating mass matter, and serve as routine replacement components during maintenance. They are also handy when diagnosing driveline drag or imbalance.
