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

TB04 aluminium front rocker

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 part replaces the factory plastic rocker to stiffen the connection between the upper suspension assembly and the shock tower.

Installation is straightforward for anyone comfortable with TB04 mechanics: remove the original rocker and transfer any existing pins or bearings. No adjustments to servo, ESC, motor, or gearbox are required because fitment is specific to the TB04 suspension layout.

In tuning terms the aluminium rocker reduces flex along the front suspension path, helping to deliver more consistent camber reaction and better-controlled roll characteristics, which is valuable when setting up for sealed circuits or carpet.
