46 mm TRF Swing Shafts, RC accessory, aluminium

These TRF 46 mm aluminium half cardan shafts add a focused drivetrain upgrade for compatible RC chassis, combining low weight with a ball bearing mounted layout that helps the axle rotate with less friction. In running, that reduced drag supports steadier power delivery through direction changes, where speed loss at the shaft can affect how cleanly a car carries momentum. The set contains 2 lightweight 46 mm swing axles and is intended as a chassis-specific accessory rather than a universal fit part. The half cardan design suits drivetrain maintenance, replacement work and targeted tuning where the shaft assembly is a key wear point. For TRF421X use, the specification names compatibility with ball bearing set 51762 and differential joints 51764 when the shafts are installed on the TRF421 chassis 42384. That combination gives a clear reference for planning a matching drivetrain setup instead of mixing unspecified parts. On the bench, the defined 46 mm length helps identify the correct shaft format before installation. During track use, the ball bearing mounted construction supports smoother axle movement in repeated corner entries and exits, where friction control matters most in a responsive RC drivetrain.
