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

Aluminum Rear Upper Arms for Hotshot

The JAZRIDER JR-THS05-LB is an aluminum rear upper suspension arm set designed for RC-scale TAMIYA Hotshot and Super Hotshot chassis. These arms replace the stock plastic pieces to offer a firmer mounting point for the rear suspension and a consistent geometry for tuning.

Compatibility is limited to the Hotshot family named in the product title. The parts are finished in blue anodizing and are intended as hop-up components for hobby-grade model cars, not for any real vehicle use.

Installation notes: the arms fit in place of the original rear upper arms without chassis modification on compatible Hotshot variants. Inspect existing hinge pins and retainers during fitment and test range of motion before final tightening. The aluminum arms change suspension response, so expect to revisit shock and toe settings after installation.

Tuning role: as metal hop-ups, these rear upper arms reduce flex at the suspension mounting points, which helps keep alignment under load and can make handling more predictable when adjusting camber and roll behavior on carpet or dirt tracks. They are a straightforward upgrade for hobbyists looking to stabilise rear-end behavior.

These aluminium rear upper arms offer a durable hop-up option for TAMIYA Hotshot chassis where firmer suspension pick-up points are desired, and they integrate into tuning workflows without major layout changes.
