Tamiya M04/M04M Rear Swing Shaft Ver 2 M03M-11/V2 by 3Racing  [M03M-11/V2]

Part Summary

The 3Racing M03M-11/V2 swing shaft is an RC-scale replacement designed to fit the Tamiya M04 and M04M rear suspension. As a direct-fit hop-up, the Ver 2 shaft restores smooth linkage motion while keeping the original suspension geometry intact.

Built for routine servicing and minor setup work, this component is intended for model use only and not for full-size applications.

Fitting follows standard M04-series rear suspension procedures. Remove the rear sub-assembly, inspect pins and bearings for wear, install the shaft assembly and confirm free articulation through the full travel. After fitting, check for binding and ensure adequate clearance to the chassis and suspension arms.

Use this part as a scheduled wear replacement or when validating handling after adjustments to shock damping, sway bars, or drivetrain components to maintain consistent rear-end behaviour.
