TAMIYA Hotshot Rear Upper Suspension Arms Aluminum Upgrade - JR-THS05-LB by Jazrider  [JR-THS05-LB]

Precision Aluminum Rear Upper Arms for Hotshot

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

Compatibility is limited to the Hotshot family listed in the title. The parts are supplied with a blue anodized finish and are intended as hop-up components for hobby models, not for use on real vehicles.

Installation notes: these arms typically install in place of the original rear upper arms without requiring chassis modification on compatible Hotshot variants. Check hinge pins and retainers during fitment and verify full range of motion before final tightening. Because the aluminum arms alter suspension stiffness, you may need to revisit shock and toe settings after fitting.

Tuning role: as metal hop-ups, these rear upper arms reduce flex at suspension attachment points, which helps preserve alignment under load and can make handling more predictable when dialling camber and roll behaviour on carpet or dirt surfaces. They are a straightforward upgrade for hobbyists wanting a more stable rear end.

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 slot into common tuning workflows without major layout changes.
