This aftermarket lower arm set is supplied as a front and rear pair tailored for the TAMIYA TT02 chassis. The items are machined from aluminium alloy to reduce flex in comparison to stock plastic arms, and they mount to the TT02's existing lower-arm points.
Fitting uses the standard TT02 suspension removal and replacement routine while keeping original mounting geometry. No specialist tooling is required beyond standard hobby tools, and the arms are compatible with the original suspension links and pins in typical installations.
From a tuning viewpoint, alloy lower arms increase lateral stiffness at the lower suspension mounts, which can sharpen steering and change chassis feedback during cornering. Use these alongside shock and anti-roll adjustments plus tyre selection to achieve balanced handling.
