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

TB04 front rocker replacement

This aluminium front rocker arm is an aftermarket replacement for the Tamiya TB04 chassis, supplied as 1pr for direct installation into TB04 front suspension assemblies. The aluminium component replaces the original plastic rocker to provide a stiffer connection between the upper suspension elements and the shock tower.

Installation follows standard TB04 procedures: remove the stock rocker, transfer any existing pins or bearings, and refit. No modifications to the servo, ESC, motor, or gearbox are required because the part is designed to match TB04 suspension geometry.

From a setup standpoint the aluminium rocker arm reduces flex through the front suspension path, improving consistency in camber response and roll behaviour which assists precise tuning for on-road and indoor surfaces.
