Tamiya TB04 Front Rocker Arm aluminium by GPM TB4027  [TB4027]

Front rocker arm for TB04

This aluminium front rocker arm is an RC-scale replacement part produced for the Tamiya TB04 platform, supplied as 1pr and intended for direct-fit use on TB04 front suspension assemblies. The component replaces the standard plastic rocker arm with a stiffer aluminium unit to provide a firmer linkage between the upper suspension elements and the shock tower.

Installation is straightforward for hobbyists familiar with TB04 internals, requiring removal of the original rocker arm and transfer of any existing pins or bearings. No changes to the servo, ESC, motor, or gearbox are needed for fitment because the part is a chassis-specific suspension linkage.

In tuning terms this aluminium rocker arm reduces flex in the front suspension path, which helps when adjusting camber response and roll characteristics; it is often selected when seeking a more consistent front-end feel for on-road or carpet setups.
