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

TB04 aluminium front arm bulk upgrade

This aluminium front arm bulk is an aftermarket replacement crafted for the Tamiya TB04 chassis. It is intended to replace the stock plastic front bulkhead and provide a firmer mounting platform for steering components and front suspension links.

The aluminium construction focuses on chassis stability rather than altering suspension geometry. Replacing the plastic bulkhead with metal reduces unwanted flex, helping maintain predictable steering response during corner entries and when fine tuning camber and caster from the front arm mounts. The part aligns with standard TB04 front mount points and uses existing hardware locations.

Fitment is a direct replacement at the TB04 front; verify clearances and compatibility with other hop-ups before finishing installation. This is a scale RC tuning component designed for model use only.
