TAMIYA M05 Rear Pin Graphite Stiffener M05-07/WO by 3Racing  [M05-07/WO]

Rear suspension pin stiffener matched to TAMIYA M05

This graphite rear suspension pin stiffener is an aftermarket hop-up for the TAMIYA M05 chassis, engineered to lower flex where the rear pin interfaces with the suspension and to give a more consistent rear behaviour when changing setup. It installs as a direct replacement and preserves the original chassis geometry.

Fitting is straightforward for model builders used to rear-end work: remove the stock pin or plate, place the stiffener into the same mounting points and tighten using the original fasteners. Only common RC hand tools are required and compatibility is maintained with standard M05 rear parts.

In a typical tuning workflow this stiffener helps firm the rear end and stabilise small steering inputs, working alongside spring and damper changes and toe tuning. As a graphite component the effect is mechanical stiffness rather than an electronic change.
