TAMIYA M07 Dynamic Swing Shaft M07-07A upgrade by 3Racing  [M07-07A]

M07 rear swing shaft summary

This replacement swing shaft is an aftermarket drivetrain link produced for the TAMIYA M07 platform and supplied under part number M07-07A. It is intended to alter the way the rear transmission and suspension interact during travel to provide a different feel under load.

Functionally the shaft modifies torque transfer as the suspension articulates, making it a tuning item to adjust rear grip and transient stability. Test its effect alongside ride height, damper settings and toe adjustments rather than expecting a single fix for handling traits.

Fitting the shaft needs partial disassembly of the rear differential carrier or transmission area to reach the original shaft location; use correct hex drivers and retain small parts. After installation check for clearances, perform a slow bench rotation test and inspect for any binding before running. Periodic checks for play and wear are recommended as part of normal maintenance.
