Tamiya TT02 Alloy Rear Adjustable Upper Arm TT2057 for tuning by GPM  [TT2057]

Product summary: rear adjustable upper arm

This aftermarket rear upper arm is produced for the Tamiya TT02 platform and identified as model TT2057. It is an alloy, adjustable link designed to replace the original plastic rear upper arm assembly and to provide a stiffer mounting point for rear suspension setup. The item is supplied as a pair to match the standard TT-02 rear hub arrangement.

The arm changes rear wheel location under load, giving hobbyists an accessible adjustment point for camber and roll-centre without modifying other suspension pieces. The alloy build increases stiffness and helps maintain repeatable mounting compared with stock parts. Installation uses the TT-02 mounting points and compatible hardware, although some projects will need replacement screws or spacers for optimal fit.

This alloy rear upper arm is a practical hop-up for TT-02 setups where firmer suspension mounts and a simple rear tuning point are desired; always check hardware compatibility before final assembly.
