Tamiya TT-01d Rear Upper Arm Alloy Precision TT057D by GPM  [TT057D]

Upper rear arm for TT-01d chassis

This alloy rear upper arm is produced as an aftermarket replacement for Tamiya TT-01d vehicles (TT057D). It is intended to serve as a direct substitute for the stock rear upper link to help maintain consistent suspension geometry.

The component sits at the rear upper link location and contributes to camber and roll-center behaviour. During installation, verify that the mounting points align and that ball-end or pivot dimensions match the TT-01d specification before final tightening. Retain the original mounting hardware unless noted otherwise in your build documentation.

Use this arm as a stable reference when modifying shock settings, roll stiffness or toe and camber angles. Keep setup records when you change parts and inspect attachment points as part of regular maintenance to ensure secure fitment.
