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

Front upper arm replacement for TT-01d

This aluminium front upper arm serves as an aftermarket replacement for the TAMIYA TT-01d platform, model TT054D. It is intended to be fitted as a like-for-like swap with the stock front upper arm for repair or incremental setup changes without modifying the chassis layout.

The arm is manufactured from aluminium alloy to provide greater stiffness than standard plastic arms. On-track that increased rigidity helps maintain suspension geometry while firming the front end, which may produce a slightly different steering characteristic and alter camber behaviour during load.

Installation uses the common TT-01d replacement steps: remove the original arm, transfer hinge pins and mounting hardware, fit the alloy arm in the same orientation, and confirm unobstructed suspension travel. After refitting, check wheel alignment and adjust toe and camber as needed for your driving preferences.

Consider this part as a passive stiffness upgrade; it works best when combined with your existing suspension settings for predictable handling. The product is supplied as an aftermarket component for hobby and track models.
