TAMIYA Hotshot / Super Hotshot Rear Upper Suspension Arms (Aluminum, Gun Metal) JR-THS05-GU by Jazrider  [JR-THS05-GU]

Aluminum Rear Upper Arms for Hotshot Series

This RC-scale set replaces the rear upper arms on TAMIYA Hotshot and Super Hotshot models. Machined from aluminum with a gun metal finish, these parts are direct-fit upgrades intended to boost durability and give a firmer mounting point versus standard plastic arms.

These components act as tuning pieces in the rear suspension, altering linkage stiffness and helping the geometry remain repeatable under load. Installation uses the stock rear upper arm mounting points, so no chassis modification is required for the listed Hotshot variants. Inspect existing fasteners for wear and reinstall using the same thread engagement.

The material and surface finish prioritise wear resistance and stable geometry rather than changing suspension kinematics; builders commonly fit matched hardware to preserve alignment and avoid galvanic contact between dissimilar metals.

For hobbyists maintaining or tuning Hotshot-series RC cars, these aluminum rear upper arms give a robust metal replacement that preserves original mounting geometry while improving longevity over plastic components.
