Aluminum Front Upper Arms for Tamiya Hotshot Series

This is an RC-scale replacement front upper suspension arm set designed for Tamiya Hotshot family models. Manufactured from anodized aluminium and finished in black, these arms reduce flex compared with stock plastic components and serve as a direct chassis-level upgrade for hobby racers and tuners seeking firmer steering feedback.

Installation follows the stock mounting points and uses the original hardware in most cases, allowing a bolt-in swap on standard Hotshot, Hotshot II/2, Super Hotshot, and Boomerang 4WD front assemblies. Expect minor setup checks after fitting, such as verifying camber and steering-link geometry to maintain intended handling balance.

Tuning role: replacing the plastic front upper arms with aluminium shifts suspension stiffness at the front axle, which can tighten turn-in and improve consistency on hard landings. Pair these with correct shock rates and roll-center adjustments rather than changing multiple components at once.

A straightforward aluminium upgrade for Hotshot-series front-end rigidity, suited to hobbyists focused on chassis consistency and sharper steering response.
