Tamiya 42385 45mm Hard Swing Shafts (2pcs) - Performance Upgrade for TRF421  [42385]

Refine TRF421 Handling with Tamiya 42385 45mm Hard Swing Shafts

Engineered for the TRF421, the Tamiya 42385 45mm hard swing shafts reduce unwanted drivetrain vibration to help the car stay composed. The 90 degree offset of the drive pin and cross shaft is key to smoothing rotational forces.

Compatibility and Strength

These shafts combine a lightweight profile with the strength required for competitive running. They are manufactured to suit the TRF421 and provide resistance to bending that can compromise handling.

Routine Maintenance

Keep pivot points free of dirt and inspect for scoring. Replace shafts showing lateral play and apply light lubrication where appropriate to maintain smooth operation.
