Tamiya TB04 Front Suspension Rocker Aluminium TB4027 by GPM  [TB4027]

Front rocker for TB04 chassis

This aluminium front rocker arm is supplied as a single pair and is intended as a direct-fit replacement for the Tamiya TB04 front suspension. It swaps the factory plastic rocker for a stiffer aluminium component to strengthen the connection between the upper links and the shock tower.

Fitting is a simple job for those used to TB04 layouts: remove the original rocker, move across any pins or bearings, and refit. No changes to electronics or drivetrain are necessary since this is a suspension-specific upgrade for the TB04.

From a tuning perspective the aluminium rocker cuts flex in the front linkage, which helps deliver steadier camber behaviour and more controlled roll transfer when fine-tuning on tarmac and carpet circuits.
