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

M07 Dynamic swing shaft overview

This is an RC-scale replacement swing shaft developed by 3Racing for the TAMIYA M07 chassis, offered as part number M07-07A. The component serves as an aftermarket drivetrain link that interacts with the rear transmission and suspension movement to influence how the drivetrain geometry changes through travel.

In practical terms the swing shaft changes the way power is transmitted during suspension articulation, so it is used as a tuning item when refining rear traction and transient behaviour. Expect to evaluate its effect together with ride height, shock setup and toe settings rather than as an isolated cure for handling issues.

Installation requires basic disassembly of the rear transmission or differential carrier to access the factory shaft location; use appropriate hex drivers and keep track of small parts. After fitting, verify clearance with surrounding parts and perform a bench rotation check before track testing. Regular inspection for wear or play is recommended as part of routine maintenance.
