TAMIYA TT-01d Alloy Front Upper Arm - TT054D by GPM  [TT054D]

Alloy front arm upgrade for TT-01d

This aluminium alloy front upper arm is an aftermarket replacement for the TAMIYA TT-01d chassis, model TT054D. It is designed as a direct swap for the stock front upper arm to serve repair and incremental tuning needs without changing the basic chassis layout.

The part uses aluminium alloy construction to increase structural stiffness over common plastic arms. On-track this produces a firmer front end that maintains suspension geometry while slightly altering steering feel and camber response under load.

Installation follows the normal TT-01d arm replacement routine: remove the original arm, transfer existing hinge pins and hardware, install the alloy arm in the same orientation, and confirm free movement through the full suspension travel. After fitting, recheck wheel alignment including toe and camber as required for your setup.

Treat this arm as a passive stiffness change rather than a geometry modifier; pairing it with your current springs and dampers will give the most predictable handling. This aftermarket alloy component is intended for model car use on track and for hobby running.
