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

Tamiya Hotshot Series Aluminum Front Upper Arms

This RC-scale replacement set fits the Tamiya Hotshot family, offering anodized aluminium construction finished in black to cut down flex versus stock plastic arms and deliver firmer steering feel for club racers and weekend tuners.

Installation uses the stock mounting points and typically accepts the original hardware, allowing a straightforward bolt-in swap on Hotshot, Hotshot II/2, Super Hotshot and Boomerang 4WD front assemblies. After fitting, check camber and steering-link geometry to retain the intended handling balance.

Tuning note: swapping plastic upper arms for aluminium increases front-end stiffness, which usually tightens turn-in and improves consistency on hard landings; adjust shock rates and roll-center settings instead of changing multiple parts at once.

A direct aluminium upgrade that improves front-end rigidity and steering precision for Hotshot-series rigs aimed at consistent handling.
