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

Precision alloy front upper arm for TT-01d

This aluminium alloy front upper arm is an aftermarket replacement designed for the TAMIYA TT-01d chassis, model TT054D. It is supplied to perform as a direct swap for the stock front upper arm and to support repair or incremental setup changes without altering the chassis mounting geometry.

The component uses an aluminium alloy construction to increase component stiffness relative to typical plastic arms. That increase in rigidity preserves the intended suspension geometry while producing a firmer front-end characteristic that can influence steering feel and camber response under load.

Standard installation applies: remove the factory arm, transfer hinge pins and original hardware, mount the alloy arm in the correct orientation, and confirm unrestricted suspension travel. After installation, verify wheel alignment and adjust toe and camber to suit your tuning objectives.

Consider this arm a passive stiffness upgrade that integrates with existing shock and spring settings to deliver predictable handling. It is intended for model car hobby and track use where a durable alloy replacement is required.
