This aluminium front upper arm set fits the Tamiya Hotshot lineup and is anodized in black to provide reduced flex compared with the OEM plastic pieces, giving clearer steering feedback for setup-minded drivers.
They install using original mounting locations and usually the stock fasteners, allowing a simple swap on Hotshot, Hotshot II/2, Super Hotshot and Boomerang 4WD. After replacement, fine-tune camber and shock settings to exploit the increased front stiffness.
Performance tip: upgrading to aluminium changes the suspension stiffness curve at the front axle, which can improve initial turn-in and repeatability. Pair this change with incremental shock-rate or anti-roll adjustments rather than wholesale setup swaps.
A tuning-oriented aluminium upgrade that helps drivers refine front-end response and consistency on Hotshot platforms.
