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

Rear suspension pin stiffener for TAMIYA M05

This graphite rear suspension pin stiffener is an RC-scale hop-up intended for the Tamiya M05 chassis, designed to reduce flex at the rear pin interface and give a more consistent rear-end feel during setup changes. The part serves as a direct-replacement stiffener that installs into the stock rear suspension pin location without altering the chassis geometry.

Installation is straightforward for hobbyists familiar with basic rear-end disassembly: remove the stock rear pin or plate, fit the stiffener into the same mounting points, and secure using the original hardware. No special tooling beyond common RC hand tools is required, and the unit is compatible with standard M05 rear suspension components.

In a tuning workflow this stiffener is used to tighten rear response and stabilise small steering inputs, pairing well with spring, damper, and toe adjustments. Because it is an RC-scale accessory made from graphite, expect a change in component stiffness rather than electronic or servo-related behavior.
