TAMIYA TB04 Aluminium Rear Shock Tower by GPM TB4030  [TB4030]

Aluminium rear shock tower for TB04

This aluminium rear shock tower is produced for the TAMIYA TB04 platform and supplied under the GPM TB4030 designation. It serves as a direct aftermarket replacement part for the TB04 rear shock tower mounting area, providing a metal alternative to the stock component for hobby-scale tuning and setup work.

In practical terms the part is intended to act as a rigid mounting point for the rear shocks and upper links. When used on the TB04 chassis it helps maintain fixed geometry under load, which assists in repeatable suspension adjustments and setup comparisons during track testing or model-level development.

Installation is straightforward for users familiar with TB04 maintenance: the tower replaces the original rear shock mount and reuses the existing mounting points and fasteners on the chassis. Because this is an aftermarket aluminium component, check alignment and thread engagement during fitment and verify shock positions before final tightening to preserve intended suspension geometry.

Tuning role: the tower is a chassis-level tuning item—use it when you want a stable reference for comparing shock positions, spring choices, or arm geometry changes. It is positioned as a structural component that supports rear suspension diagnostics and iterative setup, rather than an electronic or dynamic tuning device.
