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

Hardened 44mm swing shaft for BD5 and BD7

This 44mm swing shaft has been supplied as a heavy duty replacement for YOKOMO BD5 and BD7 1/10 on-road cars. It aims to offer improved resistance to flex and wear compared with the stock swing shaft when running higher torque or upgraded drivetrains.

Installation notes: fit the shaft into the existing steering and suspension carrier, using the original BD5 and BD7 mounting locations and hardware. During installation verify shaft clearance, driveline alignment and running clearances, and ensure 走珠軸承 (ball bearing) seating and axle alignment are correct before you torque hardware.

Tuning advice: upgrading to this 44mm heavy duty shaft can reduce component deformation under load, helping to keep drivetrain inputs consistent during acceleration out of corners. Always pair the swap with routine setup checks rather than expecting a single part to eliminate handling problems.
