YOKOMO BD5/BD7 44mm On-Road Swing Shaft YO-02A by 3Racing  [YO-02A]

Track-focused 44mm swing shaft for BD5 and BD7

This 44mm swing shaft is provided as a heavy duty replacement for YOKOMO BD5 and BD7 1/10 on-road chassis, aimed at drivers wanting a more robust driveline component than the standard shaft.

Installation notes: fit the shaft into the original steering and suspension carrier, using the stock mounting holes and hardware on BD5 and BD7 models. During fitment confirm driveline alignment, shaft clearance and that 走珠軸承 (ball bearing) seats correctly before final tightening.

Tuning guidance: increasing swing shaft strength with a 44mm heavy duty unit reduces flex under load and can give a more consistent throttle response exiting corners, but handling improvements depend on whole-car setup and should be verified with incremental adjustments.
