TAMIYA M07 Rear Dynamic Swing Shaft M07-07A performance part by 3Racing  [M07-07A]

Overview of the M07 swing shaft

This aftermarket swing shaft carries part number M07-07A and is made to change rear drivetrain geometry on TAMIYA M07 cars. It links the transmission area to suspension motion, influencing how power flows as the rear end moves.

In use the shaft alters torque distribution while the suspension articulates, so it is most effective as part of a setup process focused on rear traction and transient handling. Combine its use with adjustments to ride height, shock damping and toe rather than treating it as a standalone cure.

Installation involves opening the rear differential or transmission housing to access the original shaft location; use suitable hex tools and store small components safely. After fitting confirm there is no contact with nearby parts, rotate the drivetrain by hand to check smoothness, and include the shaft in routine wear inspections.
