Tamiya TB04 Front Rocker Arm Aluminium - TB4027 by GPM  [TB4027]

TB04 front suspension rocker

This aluminium front rocker arm is an aftermarket replacement made for the Tamiya TB04 chassis, supplied as 1pr and intended for a direct fit into TB04 front suspension assemblies. The aluminium unit replaces the stock plastic rocker to give a firmer linkage between the upper suspension parts and the shock tower.

Installation is straightforward for hobbyists familiar with TB04 internals: remove the original rocker and transfer any existing pins or bearings. There is no need to alter the servo, ESC, motor, or gearbox because the piece is a chassis-specific suspension linkage.

In setup terms the aluminium rocker arm reduces flex in the front suspension path, helping to stabilise camber reaction and refine roll behaviour; it is commonly chosen when targeting a more consistent front-end feel on on-road and carpet layouts.
