Tamiya TT-02 Aluminum Rear Upper Adjustable Suspension Arm - TT02-13121-RD by Jazrider  [TT02-13121-RD]

This aluminum rear upper adjustable suspension arm is an RC-scale accessory designed for the Tamiya TT-02 chassis. Machined aluminum and a red anodized finish provide a direct replacement for stock rear upper arms where a firmer mounting point is required.

The part is used to set and fine-tune rear camber and rear-end tracking during setup. Replacing the stock plastic arm with this aluminum unit reduces flex at the upper suspension mounting, yielding more consistent handling across laps when optimising ride balance for on-road running.

Installation is straightforward for hobbyists familiar with TT-02 layouts: remove the original rear upper arm, transfer any necessary spacers or hardware, and fasten the aluminum arm into the same mounting points.
