Tamiya TB04 Aluminium Front Arm Bulk TB4008 by GPM  [TB4008]

Front arm bulkhead in aluminium for TB04

This aluminium front arm bulk is an aftermarket RC-scale replacement part made for the Tamiya TB04 platform. It replaces the stock plastic front bulkhead to give a firmer mounting point for steering and suspension links on TB04-based cars.

As a metal upgrade, the component focuses on reducing flex rather than changing suspension geometry. Moving from plastic to aluminium helps maintain consistent steering feel through corners and when adjusting camber or caster via the front arm mounts. The unit uses the existing TB04 front mounting positions and installs with the chassis standard hardware points.

Installation is a direct swap at the TB04 front end; check fitment with your chassis and any other hop-ups before final assembly. This part is intended for RC model use and tuning on TB04 cars, and is not suitable for full-size vehicle applications.
