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

TB04 front arm bulk made from aluminium

This aluminium front arm bulk is an aftermarket replacement made for the Tamiya TB04 chassis. It is intended to swap in for the stock plastic front bulkhead and offer a firmer mounting location for steering and front suspension linkages.

The design prioritises tuning stability rather than altering the TB04 suspension geometry. Replacing plastic parts with aluminium reduces flex, helping to maintain consistent steering response during cornering and when adjusting camber or caster via the front arm mounts. The component uses the TB04 front mounting points and standard chassis hardware positions.

Fitment is a direct front-end replacement; verify compatibility with other hop-ups before use. This product is meant for RC model tuning and testing on TB04 cars and is not for full-size vehicle application.
