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

Rear upper arm overview for TT-02

This aftermarket rear upper arm is designed for the Tamiya TT02 platform and carries the model number TT2057. It is an alloy, adjustable link intended to replace the stock plastic upper arm assembly and provide a stiffer mounting point for rear suspension tuning. The item is supplied as one pair to fit the standard TT-02 rear hub arrangement.

In use the arm modifies how the rear wheel tracks under load, offering builders a discrete adjustment point for camber and roll-center behaviour without altering other suspension members. The alloy construction increases rigidity and helps preserve consistent mounting geometry versus stock plastic parts. Installation uses the TT-02 attachment points and compatible hardware, though some builds may require replacement or upgraded screws and spacers.

This alloy rear upper arm is a targeted hop-up for TT-02 users seeking firmer suspension mounting and a straightforward point for rear-end tuning; confirm hardware fitment with your particular build before final assembly.
