Tamiya Hotshot/Hotshot II/Super Hotshot/Boomerang 4WD Compatible Front Upper Arms JR-THS04-BK by Jazrider  [JR-THS04-BK]

Replacement Front Upper Arms for Tamiya Hotshot Platforms

This front upper arm kit is a direct replacement for Tamiya Hotshot-series models, crafted from anodized aluminium and finished in black to reduce flex and maintain consistent steering input compared with the original plastic arms.

Fitment follows the OEM mounting locations and commonly uses the original hardware, enabling a bolt-on swap for Hotshot, Hotshot II/2, Super Hotshot and Boomerang 4WD front ends. After installing, verify steering-link geometry and toe settings to keep handling predictable.

Notes on handling: aluminium arms stiffen the front track slightly, which can alter roll behavior and turn-in; retune shocks and camber as needed to restore the desired balance without changing multiple items at once.

A tidy aluminium upgrade that preserves fitment while improving front-end stiffness and steering consistency on Hotshot vehicles.
