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

Rear arm overview and purpose

This aftermarket rear upper arm is intended for the Tamiya TT02 platform and is listed under model TT2057. It is an alloy, adjustable link designed to replace the stock plastic rear upper arm assembly and provide a firmer, more consistent mounting point for rear suspension adjustments. The component is supplied as a single pair to suit the standard TT-02 rear hub layout.

The arm modifies how the rear wheel sits under load, giving drivers a clear adjustment point for camber and roll-centre changes without altering other suspension members. Alloy construction delivers greater rigidity and repeatable fitment compared with stock plastic parts. Fitting uses the TT-02 attachment points and compatible hardware, though some cars may require replacement screws or spacers to ensure correct assembly.

This alloy rear upper arm is a targeted upgrade for TT-02 owners looking for firmer suspension mounting and an easy rear tuning point; always check fit and hardware before completing assembly.
