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

Machined aluminium rear tower for TB04

This machined aluminium rear shock tower is manufactured for the TAMIYA TB04 platform and carries the TB4030 model marking. It is offered as a direct aftermarket replacement for the stock rear shock mount, supplying a metal alternative suited to hobbyists who want improved mounting consistency during setup work.

Functionally the component provides a rigid anchor for the rear shocks and upper link points. When fitted to a TB04 chassis it helps the rear geometry remain consistent under load, which makes suspension adjustment comparisons and track testing more reliable.

Fitment is straightforward for those experienced with TB04 maintenance: the tower replaces the original rear shock mount and uses the existing chassis mounting points and hardware. As an aftermarket aluminium item, confirm alignment and thread engagement during installation and check shock positions before final torque to protect suspension geometry.

Setup use: the tower acts as a chassis-level reference part for comparing shock positions, spring rates, or arm geometry changes rather than changing suspension dynamics by itself. Use it when you need a stable baseline for tuning sessions.
