Precision Rear Upper Arms

This RC-scale rear upper suspension arm set fits TAMIYA Hotshot and Super Hotshot models. Each piece is machined from aluminum and finished in gun metal to act as a direct replacement for the stock rear upper arms, offering improved durability and a firmer mounting point compared with plastic originals.

The parts are used for tuning the rear suspension, affecting linkage stiffness and helping the chassis keep consistent geometry under load. They mount using the OEM rear upper arm points, so no chassis modification is required for the specified Hotshot variants. Inspect and confirm the condition of fasteners before reassembly and maintain original thread engagement.

The material choice and finish prioritize wear resistance and consistent dimensions rather than changing suspension kinematics; many builders install matched hardware to maintain alignment and reduce galvanic contact between differing metals.

These aluminum rear upper arms are a practical upgrade for Hotshot-series enthusiasts seeking a stronger, metal alternative that preserves original mounting geometry.

What advantage do metal arms give over plastic?

Metal arms are more resistant to wear and impact, offering a firmer mounting point and more consistent geometry over time compared with plastic parts.

Are these a direct bolt-on replacement?

Yes. They install at the OEM rear upper arm mounting points without the need for chassis modifications on the stated Hotshot models.

How should I prevent galvanic corrosion?

Use compatible or coated fasteners and avoid direct contact between bare dissimilar metals; matched hardware helps minimise corrosion risk.

Does the product keep original geometry?

Yes. The design preserves original mounting geometry so suspension kinematics remain consistent while offering a metal upgrade.
