Tamiya M04M Rear Suspension Swing Shaft M03M-11/V2 by 3Racing  [M03M-11/V2]

Overview and Fitment

The 3Racing M03M-11/V2 swing shaft is an aftermarket RC component created for the Tamiya M04 and M04M rear suspension. As a Ver 2 direct-fit item, it aims to recover smooth rear linkage motion while preserving the stock geometry.

Its intent is practical: provide a replaceable shaft for routine servicing and modest tuning tasks. This item is for model use only.

Installation follows the usual M04 rear procedure. Remove the rear sub-assembly, check pins and bearings for wear, replace the shaft assembly and confirm free travel throughout suspension movement. After fitting, make sure there is no binding and that clearance to the chassis and arms remains correct.

Consider this part a wear item suitable for restoring predictable handling or for use when assessing changes to damping, roll stiffness, or drivetrain components.
