3RACING 3.0mm Aluminum Single Servo Arm for Ko Propo/Sanwa - Purple - 3RAC-HKS30F/PU  [3RAC-HKS30F/PU]

Stiff aluminium servo arm for sharper control

The 3Racing 3.0mm Aluminium Single Servo Arm is a straightforward upgrade for models using Ko Propo or Sanwa systems. Its purple anodised surface adds a distinctive look while keeping linkages solid under load.

Optimised for steady inputs

Manufactured to reduce flex in the control linkage, this arm supports cleaner steering and throttle actions. It is particularly useful where consistent response matters during aggressive driving.

Quality build meets track-ready styling

Constructed from aluminium for durability, the arm holds up to regular hobby use and resists wear better than plastic alternatives. The purple finish remains attractive with routine care.
