TAMIYA Hotshot/Super Hotshot Aluminum Rear Upper Arms (Blue) - JR-THS05-LB by Jazrider  [JR-THS05-LB]

High-Strength Rear Upper Arms for Hotshot

The JAZRIDER JR-THS05-LB kit contains aluminum rear upper suspension arms for the TAMIYA Hotshot and Super Hotshot chassis. These units replace the original plastic arms to provide a firmer suspension pickup and more reliable geometry for setup work.

Intended application is limited to the Hotshot models specified in the listing. The blue anodized finish protects the aluminium and is supplied as a hobby-grade hop-up; these are not intended for any real vehicle use.

Fit notes: the arms generally mount in the same position as the OEM rear upper arms on compatible Hotshot variants without chassis alteration. Confirm hinge-pin fit and retainer positioning during installation and test articulation before final torque. Because aluminium reduces flex at the mounting points, handling characteristics will change and may need alignment and shock tuning.

Role in tuning: metal rear upper arms minimise flex where the suspension attaches to the chassis, helping with camber control under load and making rear behaviour more predictable when adjusting suspension settings for different track conditions.

These aluminium rear upper arms are a sensible hop-up for Hotshot owners seeking less flex at suspension mounts and a more controlled tuning platform.
