Tamiya TT-02 Aluminum Rear Upper Adjustable Suspension Arm by JAZRIDER TT02-13121-RD  [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 more rigid mounting point is desired.

Functionally 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 mounting point of the suspension, which can produce more consistent handling across laps when tuning ride balance for on-road use.

Installation is straightforward for hobbyists familiar with TT-02 layouts: remove the original rear upper arm, transfer any required spacers or hardware, and secure the aluminum arm in the same mounting locations.
