TAMIYA GF01/TL01 Rear Lower Arm Aluminium Upgrade GF056 by GPM  [GF056]

Rear lower arm overview

This aluminium rear lower arm is an aftermarket option for 1/10 scale TAMIYA GF01 and TL01 chassis. It is a direct replacement for the stock plastic arm, keeping the same mounting geometry while swapping the material to aluminium to change flex and long-term wear behaviour.

In a practical setup the aluminium arm is used when drivers want a firmer rear end and reduced wear at pivot points. It alters how the suspension responds across multiple runs and is often paired with shock valving or anti-squat tuning for a balanced setup.

The part ships as a pair intended only for the rear lower arm positions and is designed strictly for RC chassis use rather than full-scale vehicles.

Fit these arms when consistent pivot performance and a firmer rear end are priorities, and verify alignment on your GF01 or TL01 during setup changes.
