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

44mm swing shaft for YOKOMO BD5/BD7

This 44mm swing shaft from 3Racing is supplied as a heavy duty replacement for YOKOMO BD5 and BD7 1/10 on-road chassis. It is intended as an RC-scale drivetrain component to replace the stock swing shaft and address durability in higher-load setups.

Installation notes: the part installs into the existing steering/suspension carrier and uses the original mounting points and hardware on BD5 and BD7 chassis. Check shaft fit, driveline alignment and running clearance during installation, and confirm that走珠軸承 (ball bearing) seating and axle alignment are correct before final tightening.

Tuning role: swapping to a heavier-duty 44mm shaft reduces component flex under increased torque or aggressive corner exits, which can stabilise drivetrain response and help maintain consistent traction during track use. Pair changes with basic setup checks rather than assuming a single part will fix handling issues.
