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

Product Overview

The M03M-11/V2 swing shaft from 3Racing is an RC-scale replacement part compatible with the Tamiya M04 and M04M rear suspension. This Ver 2 hop-up is intended to restore reliable linkage movement without modifying primary geometry.

Provided for maintenance and cautious tuning work, the unit is intended for model applications only and is not for full-size use.

Fitting is the standard M04-series routine: remove the rear sub-assembly, inspect pins and bearings, fit the new shaft and verify smooth articulation over full travel. After installation, ensure there is no binding and that clearance to the chassis and suspension arms is correct.

Use this shaft as a routine replacement when restoring handling consistency or when testing rear-end setup changes like shock rates or anti-roll adjustments.
