This set provides RC-scale rear upper suspension arms specifically for TAMIYA Hotshot and Super Hotshot chassis. The parts are precision-machined from aluminum with a gun metal finish and fit as direct replacements to improve durability and provide a firmer mounting point compared to stock plastic arms.
They serve a tuning purpose within the rear suspension, influencing linkage stiffness and helping preserve geometry through loaded conditions. Fitting uses the OEM rear upper arm mounting points, so no chassis modifications are required for the listed Hotshot models. Inspect fasteners for wear and ensure proper thread engagement when reinstalling.
The finish and material are selected to prioritise wear resistance and dimensional consistency rather than altering suspension kinematics; installers frequently use matched hardware to maintain alignment and reduce the chance of galvanic contact between different metals.
These aluminum rear upper arms are a reliable metal upgrade for Hotshot-series RC cars, preserving factory mounting geometry while offering greater strength than plastic components.
